Q2. Explain best efficency point of centrifugal pump
Ans. 
The best efficiency point of a centrifugal pump is the operating point where the pump achieves the highest efficiency.
• The best efficiency point is typically located near the pump's BEP (Best Efficiency Point) on the pump curve.

• At the best efficiency point, the pump operates with the least amount of energy consumption and highest output.

• Operating the pump away from the best efficiency point can lead to decreased efficie...read more

Q3. Explain joule Thomson effect
Ans. 
Joule Thomson effect is the change in temperature of a gas when it is allowed to expand without performing work.
• Occurs when a gas expands through a valve or porous plug

• No external work is done on or by the gas

• Temperature change depends on the gas properties and initial conditions

• Used in natural gas processing to cool the gas for further processing

Q5. Explain series and parallel operation of pumps
Ans. 
Series and parallel operation of pumps involve connecting multiple pumps together to achieve desired flow rates and pressures.
• In series operation, pumps are connected one after the other to increase the total head or pressure that the system can deliver.

• In parallel operation, pumps are connected side by side to increase the total flow rate that the system can deliver.

• Series operation is used when high pressure is requi...read more
