This document provides an overview of applied fluid dynamics related to pumps. It discusses various pump types including positive displacement and kinetic pumps. Positive displacement pumps are further divided into rotary and reciprocal types. Rotary positive displacement pumps include gear, screw, progressive cavity, lobe and peristaltic pumps. Reciprocal positive displacement pumps include piston and diaphragm pumps. Kinetic pumps discussed are centrifugal and axial flow pumps. The document also covers pump performance parameters such as head, efficiency and NPSH. Cavitation is explained as a phenomenon caused by vapor bubbles forming due to a drop in pressure below the vapor pressure. Methods to calculate NPSHA and determine if cavitation will occur are presented along with an example problem.

Accumulation and Over-pressure: difference between accumulation and overpressureVarun Patel
Accumulation is pressure above the maximum allowable working pressure that vessel experience during high pressure event. Hence, when we say ‘accumulation’, its mean we are talking about the vessel or equipment.
On the other hand, Overpressure is pressure above the set pressure of the pressure safety valve that PSV experience during high pressure event. Hence, when we say ‘accumulation’, its mean we are talking about the pressure relief valve.

Safety is the most important factor in designing a process system. Some undesired conditions might happen leading to damage in a system. Control systems might be installed to prevent such conditions, but a second safety device is also needed. One kind of safety device which is commonly used in the processing industry is the relief valve. A relief valve is a type of valve to control or limit the pressure in a system by allowing the pressurised fluid to flow out from the system.
CENTRIFUGAL COMPRESSOR SETTLE OUT CONDITIONS TUTORIALVijay Sarathy
Centrifugal Compressors are a preferred choice in gas transportation industry, mainly due to their ability to cater to varying loads. In the event of a compressor shutdown as a planned event, i.e., normal shutdown (NSD), the anti-surge valve is opened to recycle gas from the discharge back to the suction (thereby moving the operating point away from the surge line) and the compressor is tripped via the driver (electric motor or Gas turbine / Steam Turbine). In the case of an unplanned event, i.e., emergency shutdown such as power failure, the compressor trips first followed by the anti-surge valve opening. In doing so, the gas content in the suction side & discharge side mix.
Therefore, settle out conditions is explained as the equilibrium pressure and temperature reached in the compressor piping and equipment volume following a compressor shutdown

Improving Energy Efficiency of Pumps and Fanseecfncci
Pumps and Fans are energy consuming equipment that can be found in almost all Industries. Therefore, it is important to check if they are running efficiently. This presentation give an overview about energy saving opportunities in pump and fan equipment. It was prepared in the context of energy auditor training in Nepal in the context of GIZ/NEEP programme. For further information go to EEC webpage: http://eec-fncci.org/
Pumps are used in virtually all industries and are big uses of energy. This presentation shows methods of condition monitoring and how to optimise time to overhaul.
This presentation covers process safety considerations and when a dynamic simulation is required. We also provide a modelling approach and a case study on Coker Bottoms Steam Generator, which includes information on device selection and device sizing.
Generally Pumps classification done on the basis of its mechanical configurat...ShriPrakash33
Pumps simplify the transportation of water and other fluids, making them very useful in all types of buildings - residential, commercial, and industrial. For example, fire pumps provide a pressurized water supply for firefighters and automatic sprinklers, water booster pumps deliver potable water to upper floors in tall buildings, and hydronic pumps are used in HVAC systems that use water to deliver space heating and cooling.
TYPES OF PUMPS AND THEIR WORKING PRINCIPLES
Generally Pumps classification done on the basis of its mechanical configuration and their working principle. Classification of pumps mainly divided into two major categories:
Dynamic pumps / Kinetic pumps
Dynamic pumps impart velocity and pressure to the fluid as it moves past or through the pump impeller and, subsequently, convert some of that velocity into additional pressure. It is also called Kinetic pumps Kinetic pumps are subdivided into two major groups and they are centrifugal pumps and positive displacement pumps.
Classification of Dynamic Pumps
1.1 Centrifugal Pumps
A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically. The energy changes occur by virtue of two main parts of the pump, the impeller and the volute or casing. The function of the casing is to collect the liquid discharged by the impeller and to convert some of the kinetic (velocity) energy into pressure energy.
1.2 Vertical Pumps
Vertical pumps were originally developed for well pumping. The bore size of the well limits the outside diameter of the pump and so controls the overall pump design.2.) Displacement Pumps / Positive displacement pumps
2. Displacement Pumps / Positive displacement pumps
Positive displacement pumps, the moving element (piston, plunger, rotor, lobe, or gear) displaces the liquid from the pump casing (or cylinder) and, at the same time, raises the pressure of the liquid. So displacement pump does not develop pressure; it only produces a flow of fluid.
Classification of Displacement Pumps
2.1 Reciprocating pumps
In a reciprocating pump, a piston or plunger moves up and down. During the suction stroke, the pump cylinder fills with fresh liquid, and the discharge stroke displaces it through a check valve into the discharge line. Reciprocating pumps can develop very high pressures. Plunger, piston and diaphragm pumps are under these type of pumps.
2.2 Rotary Type Pumps
The pump rotor of rotary pumps displaces the liquid either by rotating or by a rotating and orbiting motion. The rotary pump mechanisms consisting of a casing with closely fitted cams, lobes, or vanes, that provide a means for conveying a fluid. Vane, gear, and lobe pumps are positive displacement rotary pumps.
2.3 Pneumatic Pumps
Compressed air is used to move the liquid in pneumatic pumps. In pneumatic ejectors, compressed air displaces the liquid from a gravity-fed pressure vessel through a check valve into the discharge line in a series of surges spaced by the time required.

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

• This is due to the pressure changes in the
– Inlet (Suction)
– Eye (impeller center)
– Outlet (Discharge)
• Recall that for a substance
– If the Pressure decreases
– The boiling temperature decreases
www.ChemicalEngineeringGuy.com
57. Cavitation
• So… for example water:
– If T operation = 80ºC
– Inlet = 1 atm
– Eye = 0.5 atm
– Outlet = 2 atm
www.ChemicalEngineeringGuy.com
58. • So… for example water:
– If T operation = 80ºC
– Inlet = 1 atm 100
– Eye = 0.5 atm 75
– Outlet = 2 atm 120

84. Pump Power
• Recall that we are calculating Specific Energy
– That is, Energy per unit mass
– If you multiply by all the mass involved…
– You get the total Work required
• If you use mass flow (mass per unit time)
– That Work (energy) will turn to Power (energy per
unit time)
85. Pump Power
• Power is very important in Pumping
– P= m*Wb/η
• m: mass flow (kg/s)
• Wb= Work done by Pump per unit mass (J/kg
or m2/s2)
86. Pump Power

– Mass flow is 1.3 kg/s
– Efficiency
• 80% when Wb > 2 kJ
• 72% when Wb < 2 kJ

107. System Curve Exercise #1 Conclusions
• You must note that when increasing Flow:
– You increase velocity in pipes
– Vb^2-Va^2 difference may increase (requirement of
power)
• Only when delivering in tanks (Va = Vb = 0) will not change
– Pressure in “a” and “b” will remain the same
– Heigth difference of “a” and “b” will remain the same
– Velocity increase Increase in Friction by V^2

215. Methodology for Pump Selection
1. Choose which type of pump suits best
– Use the Specific Velocity Criteria
– Use a Graph (shown afterwards)
2. Check out the different models of that type
of pump system (radial, axial, etc.)
3. Then calculate the curve of the system
4. Intersect the Pump Head Curve + System
Head
5. That’s your operation point! Optimize it!
www.ChemicalEngineeringGuy.com
216. 1a. General Pump Selection Diagram
• Easy to follow
• Function of Q and nWp (head)
• Contains basic Pumps in the Industry
• Methodology:
– Calculate Q and Head
– Intersect Q(x-axis) with Head (y-axis)
– This point is the recommended Pump
224. 1a. General Pump Selection Diagram
• Recommend a Pump with the following:
– nWp = 150 ft
– Q = 100 GPM
225. 1a. General Pump Selection Diagram

Centrifugal Pumps!
227. 1b. Specific Velocity Criteria
• A better approach is to use the Specific
Velocity/Diameter Criteria
• Better since it is Dimensionless Number
Comparison
• Calculate Ns (Specific Velocity)
• Calculate Ds (Specific Diameter)
– Find Operation Point
– Find Suggested Pumping System
www.ChemicalEngineeringGuy.com
228. 1b. Specific Velocity Criteria
• N = impeller speed (RPM)

pump
• There are many “recommended” pumps in a set of
“Families”
• Get the best that suits your system!
245. 2. Pump Supplier’s Family
• Criteria to consider:
– Max/min Impeller Size (Diameter in Inches)
– Velocity (RPM)
– Power (BHP)
– Efficiency (approx 50-90%)
– NSHP Required
– Pump Curve included
– Suction & Discharge Sizes
248. 2. Pump Supplier’s Family
• Once you get a Pump
– Check specifically the Operation of the given
pump
– Find the Operation Point
– Consider Efficiency
– Consider NPSHr
– Consider Head vs. Q ratio (Steep or flat?)
www.ChemicalEngineeringGuy.com
250. 3. Calculate System Head
• You should have this by now
– Try to set the equation in an Spread Sheet
– Probably you will change piping and flows
• This will change the Head constantly
www.ChemicalEngineeringGuy.com
Check out the exercise of the “System’s Head Exercise 1,2,3”
251. 3. Calculate System Head
• Recall that the System Head may be
manipulated
– You may increase the Head of the System:
• Slightly Closing Valves More Friction More System
Head
– You may ecreasethe Head of the System:
• Slightly Opening Valves LessFriction Less System
Head
www.ChemicalEngineeringGuy.com
253. 3. Calculate System Head
• Many Valves may operate at different %
– 0% Closed
– 10%, 20%, 50%, 99% Partially Open
– 100% Completely Open
• Partially Closing a Valve will
– increase the friction
– will maintain the same flow rate (no speed change)
