Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

4. Firefighting
Firefighting system is one of the important
and integral part of the plant from a safety
point of view as transformer oil is highly
inflammable and can cause great hazard.
Firefighting is the act of extinguishing fires.
A firefighters suppresses and extinguishes fires to
protect lives and prevent destruction of property and
the environment.
5. Necessity of Fire Fighting system
• The fire fighting system in the sub station is
very essential
• Saves the equipment from damage
• Loss of life & loss of equipment can be
prevented
• Regular trial operation of the system is
necessary to detect any fault /deficiency in the
system
6. Design & Engineering
Managing fire safety starts with the initial design of a building. The design should minimize the risk
of fire and ensure that, if a fire does occur, appropriate fire safety systems (including active, passive,
and procedural systems) are in place.
It is now compulsory for companies to conduct a fire risk assessment. As an employer, or as
someone who has control of a workplace, you must take reasonable steps to reduce the risk from
fire and make sure people can safely escape if there is a fire.
The management of fire safety is an essential element in averting disaster in the event of a fire.
Although many buildings will never have a serious life-threatening fire, it is essential for fully
functional fire safety procedures to be an integral part of every building.

11. PIPING AND FITTING
A fitting is used in pipe plumbing systems to connect straight pipe or tubing sections,
to adapt to different sizes or shapes, and for other purposes, such as regulating or
measuring fluid flow. The term plumbing is generally used to describe conveyance of
water, gas, or liquid waste in ordinary domestic or commercial environments,
Whereas piping is often used to describe high-performance.
12. FLANGE
To connect two pipe
A flange is an external or internal ridge, or rim (lip), for strength, as
the flange of an iron beam such as an I-beam or a T-beam; or for
attachment to another object, as the flange on the end of a pipe,
steam cylinder, etc., or on the lens mount of a camera; or for a
flange of a rail car.
13. SPIRIT LEVEL
To check the pipe is straight
and perpendicular or not.
RATCHET THREADER
To cut thread in the pipe
WRAPPING COATING
It is used to cover the pipe by which
water supply with the underground
system. It is used fir protection of pipe
by corrosion, destroy and leakage of
pipe is strictly prohibited. It also
increase the pipe to long life.
14. Welding is an art of joining metals by heating and then pressing
together. The process of joining may also take place by other
means of riveting or by fastening nut and bolts.
15. GAS CUTTER
Oxygen/Acetylene welding, or "Gas Welding", is a process which relies on
combustion of oxygen and acetylene. When mixed together in correct
proportions within a hand-held torch or blowpipe, a hot flame is produced with a
temperature of about 3,200°c. The chemical action of the oxy/acetylene flame
can be adjusted. by changing the ratio of the volume of oxygen to acetylene,
using the valves on the torch or blowpipe.
16. GRINDER
A grinding machine is a machine tool used for producing very
fine finishes or making very light cuts, using an abrasive wheel
as the cutting device. This wheel can be made up of various
sizes and types of stones, diamonds or of inorganic materials.
For machines used to reduce particle size in materials
processing see grinding.
HIGH SPEED CUTTER
It is used to cut the section of pipe as dimension is required in
the design to set up the pipe.
17. Gate valve
A gate valve is a linear motion valve used to start or stop fluid flow. The name gate is
derived from the appearance of the disk in the flow stream.
Strainer
It is used to prevent impurities and solid particles
from entering the pump.
Types
Y-type and basket type
18. Solenoid valve
A solenoid valve is an electromechanically operated valve. The valve is
controlled by an electric current through a solenoid in the case of a two-
port valve the flow is switched on or off; in the case of a three-port valve,
the outflow is switched between the two outlet ports. Multiple solenoid
valves can be placed together on a manifold.
Solenoid valves are the most frequently used control elements
in fluidics. Their tasks are to shut off, release, dose, distribute or mix
fluids.
A- Input side
B- Diaphragm
C- Pressure chamber
D- Pressure relief
passage
E- Solenoid
F- Output side
19. Strainer screens
Perforated screens - These are formed by punching a large number of
holes in a flat sheet of the required material using a multiple punch. The
perforated sheet is then rolled into a tube and spot welded together These are
relatively coarse screens and hole sizes typically range from 0.8 mm to 3.2 mm.
Consequently, perforated screens are only suitable for removing general pipe
debris.
Mesh screens - Fine wire is formed into a grid or mesh arrangement. This is then
commonly layered over a perforated screen, which acts as a support cage for the
mesh
20. Deluge Valve is known as a system control valve
in a deluge system, used for fast application of
water in a spray system. Deluge valve protects
areas such as power transformer installation,
storage tank, conveyor protection and other
industrial application etc. With the addition of
foaming agent they do protect aircraft hanger and
inflammable liquid .
Pressure Relief Valve
The valve maintains a pre-set fixed
upstream pressure, regardless of
downstream pressure or flow rate
variations. The valve will be closed
drip tight when the upstream
pressure is lower than the set value.
Pressure Reduce Valve
Hydraulic pressure-reducing valve.
The valve maintains a pre-set fixed
downstream pressure, regardless of
upstream pressure or flow rate
variations
21. Types of fire detectors
• Heat detectors
• Smoke detectors
• Flame detectors
Heat Detectors
• These are generally less sensitive than smoke detectors and are
unlikely to respond for smoldering fires.
• They are not suitable for the protection of places where small fires
can cause huge losses.e.g. Computer Rooms
• These are suitable for use in places where sufficient heat is likely to
be generated and damage caused the heat generated by fire
contributes top main hazards. E.g. Battery Rooms, Boilers etc
22. Microprocessor based analogue addressable fire detection
systems
• Analogue Fire Alarm System
These are also microprocessor based systems which work on the principle of
extended loops and are suitable for large premises. The system gives LED
indications in the control panel thereby isolating the source of fire.
Addressable Fire Alarm System
These systems give LCD displays which show the exact location of all the detectors
room-wise (for example computer room, drawing room etc.) from where fire has
started.
• Conventional fire detection systems:-
From control panels through to manual call points, decectors, bells, door releases
and sounders, gent by Honeywell provides a cost effective conventional fire
detection system scalable for sites of all types. With the Xerox control panel at its
hub, Gent can cover up to eight zones. Integrated with the low-current S-cube
range of sounders incorporating sound, speech and storbe in a single device, Gent
ensure a site has high levels of coverage with above average response rates during
an emergency situation.
23. FIRE HYDRANT SYSTEM
A fire hydrant is an above-ground connection that
provides access to a water supply for the purpose of
fighting fires.
The water supply may be pressurized, as in the case of
hydrants connected to water mains buried in the
street, or unpressurized, as in the case of hydrants
connected to nearby ponds or cisterns. Every hydrant
has one or more outlets to which a fire house may be
connected. If the water supply is pressurized, the
hydrant will also have one or more valves to regulate
the water flow.
24. Hose pipes along with branch pipes and
nozzles are kept in post boxes located
adjacent to hydrants points.
In case of fire, these hoses are coupled to the
respective hydrant and jet of water is
directed towards the seat of the fire.
The system is automatic to the extent that
whenever the pressure in the piping network
drops the beyond a preset value, signal is
given to start the hydrant pump by means of
pressure switch. However the stopping of the
pump is manual.
Water for the hydrant service is generally
stored in an easily accessible RCC reservoir.
The water for the hydrant system shall be
supplied from the nearest bore wells
available in the substation.
HYDRANT SYSTEM
25. SPECIFICATION
• The Hydrant system is spread in the switchyard and the
auxiliary systems
• Large pipes of dia 300mm/250mm/150mm either
underneath or above the ground runs in the yard
• Identification – post office red painted
• The pressure in the line is maintained by the air
compressor in auto mode – 7Kg/cm2
• The hydro pneumatic tank maintains the pressure and loss
of water.
• Jockey pump maintains the water level in the hydro-
pneumatic tank
• Two level switches detect the water level
26. • A special type of nozzle – projectors discharges a cone of water in the form
of evenly distributed broken streams of high velocity and high momentum.
• The rapid movement of the broken streams of water is suddenly arrested at
the oil surface and the impact causes the oil to be broken up into tiny
globules to form an emulsion with water.
• In this manner, almost immediately the water from the projector strikes the
burning oil-in-water emulsion is formed which cannot burn.
• In addition, the dispersion of the oil in minute globules in the water gives
almost instantaneous cooling and thus, together with the extinguishment of
the fire, there is simultaneous cessation of the formation of the Vapour
• Detection of fire – Quartzoid bulbs fitted in the detection line
• The Quartzoid bulbs are broken at 79Deg C thus reducing the pressure in
detection line
Emulsification process
27. SPRINKLER SYSTEM
A system for extinguishing fires; water from a network
of overhead pipes is released through nozzles that
open automatically with the rise in temperature.A fire
sprinkler system is an active fire protection measure,
consisting of a water supply system, providing
adequate pressure and flowrate to a water distribution
piping system, onto which fire sprinklers are
connected. Although historically only used in factories
and large commercial buildings, home and small
building systems are now available at a cost-effective
price.
28. WATER SUPPLIES:
• Water for the spray system shall be stored in any easily accessible
surface or under ground lined reservoir or above ground tanks of steel,
concrete, or masonry.
• Reservoirs/tank shall be in two independent but interconnected
compartments with a common sump for suction to facilitate cleaning and
repairs.
• Water for the systems shall be free of particles, suspended matters,etc. and
as far as possible, filtered water shall be used for the systems.
• Level indicator shall be provided for measuring the quantity of water
stored anytime.
• Water reservoir/tank shall be cleaned at least once in two years or more
frequently if necessary to prevent contamination and sedimentation.
• It is advisable to provide adequate inflow into the reservoir/tank so that the
protection can be reestablished within a short period.
Water Spray Systems
29. TYPES OF SPRAY SYSTEM
• Medium Velocity Water Spray System – MVWS
Fires involving liquids with flash points below 32°C cannot always be
extinguished by high velocity water spray system, and in such cases
medium velocity water sprayers giving medium water drop sizes are
employed. Water is sprayed directly over the protected surface,
preventing dangerous temperature rise and distortion.
• High Velocity Water Spray System – HVWS
High velocity water spray system has been designed to extinguish oil fires.
It introduces an entirely new principle in fire extinguishing.
High velocity water spray system has been designed to extinguish oil fires.
It introduces an entirely new principle in fire extinguishing. It is employed
to bring about a fundamental change in the nature of the flammable
liquid, which is converted temporarily into an emulsion that cannot burn.
All oils are water repellent, and so do not melt. Therefore, the cooling
action of water applied in the form of a jet or low-pressure spray is
negligible. The basic principle used in high velocity spray system is the use
of water in the form of fine mist.
30. • This system is used for the protection of transformers and reactors in the
substation.
• The High Velocity Water Spray System - for extinguishing of oil fires
• It is employed to bring about a fundamental change in the nature of the
inflammable liquid, which is converted temporarily into an emulsion which
cannot burn.
• High Velocity water spray system - network of projectors arranged around
the equipment to be protected.
• Water under pressure is directed to the projector network through a flow
control/deluge valve from a pipe network laid exclusively for the spray
system.
• The minimum running water pressure at any projector must in no instance
be below 3.5 bar.
High Velocity Water (HVW) Spray
System
31. Nozzle
Nozzle is a device which accelerates the fluid in a direction along the axis of nozzle.
Special type of nozzle – projectors discharges a cone of water in the form
of evenly distributed broken streams of high velocity and high momentum
Quartzoid Bulb Detector (QBD)
It is used for detection of fire which will be connected to the deluge valve for auto
operation of the system.
Sprinkler temperature should be of 68Deg or 79Deg Celsius depending upon the
ambient temperature of the location of the plant.
32. Pressure gauge
Water pressure is measured in pounds per square inch or psi. An average
water pressure is around 30-50 psi. The pressure can vary widely from home
to home. Determining your specific pressure is necessary to your irrigation
plan. Keep in mind that sprinkler and drip systems will not work properly if
the pressure is too low or too high. Most sprinkler systems work at an optimal
pressure of 30-50 psi, and most drip systems work best in the range of 20-40
psi.
33. It is used to reduce frictional head and give a steady flow of liquid.
Air Vessel Mild steel air vessel adequate size to take care of
pressure surges during operation of the system and venting
of entrapped air in the system shall be complete with air
relief valve, pressure gauge, drain valve and shut off valve at
the inlet.
35. ELECTRIC MOTOR
The motor or an electrical motor is a device
that has brought about one of the biggest
advancements in the fields of engineering and
technology ever since the invention of
electricity. A motor is nothing but an electro-
mechanical device that converts electrical
energy to mechanical energy
Types of electric motor
1) DC Motor
2) Induction Motor
3) Synchronous Motor
36. JOCKEY PUMP
Jockey pump is a small pump connected to a
fire sprinkler system to maintain pressure in
the sprinkler pipes. This is to ensure that if a
fire-sprinkler is activated, there will be a
pressure drop, which will be sensed by the
fire pumps automatic controller, which will
cause the fire pump to start.
DIESEL ENGINE
Diesel engine is a type of internal combustion
engine. Combustion is another word for
burning, and internal means inside, so an
internal combustion engine is simply one
where the fuel is burned inside the main part
of the engine (the cylinders) where power is
produced.
37. CONTROL PANEL
The supplier shall supply necessary control panels with instruments
mounted therein. All the interconnections between panel and
equipment will be carried out by others for which purpose the supplier
shall apply adequate quantities of tubing, wiring, fittings, terminal
boxes etc.
