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.

3. Suspension System
Introduction:
• The automobile frame and body are mounted on the front and rear
axle not directly but through the springs and shock absorbers.
• The assembly of parts, which perform the isolation of parts from the
road shocks, may be in the forms of bounce, pitch and roll is called
suspension system.
Note:
suspension system consists of a spring and damper.
The energy of road shock causes the spring to oscillate.
These oscillations are restricted to a reasonable level by the
damper, which is more commonly called as shock absorbers.
4. • Rotations:
– A roll rotation about x-axis
– A pitch rotation about y-axis.
– A yaw rotation about z-axis.
Vehicle Axis system
Basic suspension movements:
1.Bouncing: The vertical movement of the complete body.
2. Pitching: The rotating movement of all the parts between the spring and road
and the portion of spring weight itself.
3. Rolling: The movement about longitudinal axis produced by the centrifugal
force during cornering.
6. Functions of suspension system
1. It prevents the vehicle body and frame from road shocks.
2. It gives stability of the vehicle.
3. It safeguards the passengers and goods from road shocks.
4. It gives the good road holding while driving, cornering and braking.
5. It gives cushioning effect.
6. It provides comfort.
7. Requirements of suspension system
1. There should be minimum deflection.
2. It should be of low initial cost.
3. It should be of minimum weight.
4. It should have low maintenance and low operating cost.
5. It should have minimum tyre wear.
10. SPRUNG MASS
• In a vehicle with a suspension, such as an automobile, motorcycle
or a tank, sprung mass (or sprung weight) is the portion of the
vehicle's total mass that is supported above the suspension.
• The sprung weight typically includes the body, frame, the internal
components, passengers, and cargo.
• but does not include the mass of the components suspended below
the suspension components (including the wheels, wheel bearings,
brake rotors, callipers)
11. UNSPRUNG MASS
• In a ground vehicle with a suspension, the unsprung
weight (or the unsprung mass) is the mass of the
suspension, wheels or tracks (as applicable), and other
components directly connected to them, rather than
supported by the suspension.
• Unsprung weight includes the mass of components such
as the wheel axles, wheel bearings, wheel hubs, tires,
and a portion of the weight of driveshafts, springs, shock
absorbers, and suspension links.

14. Coil spring is the most common type of spring found on modern vehicles.
Leaf springs are now limited to the rear of some cars.
15. LEAF SPRINGS
• Leaf springs are formed by bending.
• They are made of long strips of steel.
• Each strip is named as Leaf.
• The long leaf is called Master Leaf, and it consists of eyes at its both ends.
• One end is fixed to the chassis frame, the other end is fixed to the shackle spring.
• The spring will get elongated during expansion and shortened during compression.
• This change in length of spring is compensated by the shackle.
• The U-bolt and clamps are located at the intermediate position of the spring.
• The bronze or rubber bushes are provided on both eyes on the master leaf.
• Originally called a laminated or carriage spring
18. Types of Leaf Springs
• There are six types of leaf springs
1.Full – elliptic type
2.Semi – elliptic type
3.Quarter – elliptic type
4.Three Quarter – elliptic type
5.Transverse Spring type
6.Helper Spring type
19.
20. 1.FULL ELLIPTIC
• The advantage of this type is the elimination of
shackle and spring.
• The lubrication and wear frequently which are
on of the main draw back of this type of
springs.
21. 2.SEMI – ELLIPTIC
• This type is more popular for rear
suspension are used in 75% of cars.
22. 3.QUARTER – ELLIPTIC
• This type is rarely used in now-a-days.
• It gives very less resistance in road shocks.
23. 4.THREE QUARTER – ELLIPTIC
• This type is rarely used in now-a-days.
• It gives resistance, but occupies more space
than other types.
24. 5.TRANSVERSE SPRING
• This type of spring is arrange transversely
across the car instead of longitudinal direction.
• The transverse spring for front axle, which is
bolted rigidly to the frame at the center and
attached to the axle by means of shackle at
both ends.
26. Helper Springs
• The helper springs are used in heavy vehicles
for rear suspension.
• When vehicle fully loaded the main spring as
well as helper spring to come in action and
absorb the road shocks.
• When the load of the vehicle is less, the helper
spring will not act and the main spring only
absorb the road shocks.
32. TORSION BAR
• Torsion bar suspension is used in independent suspension system.
• It is a rod acting in torsion and taking shear stresses only.
• It is made up of heat treated alloy spring steel.
• This bar stores amount of energy nearly as same as coil spring.
• The bar is fixed at one end to the frame, while the other end is fixed to the
end of the wheel arm and supported in the bearing.
• The other end of the wheel arm connected to the wheel hub.
• When the wheel strikes a bump, it starts vibrating up and down, thus
exerting torque on the torsion bar which acts as a spring.
46. • Shock absorbers - controls unwanted
spring motion through dampening
– compression cycle
– extension cycle
• Limits spring compression-extension
movements to smooth the vehicle’s ride.
• Without shock absorbers, the vehicle
would continue to bounce up and down
long after striking dip or hump in the road.
