Q1. What is pump hydraulic calculation?
Ans. 
Hydraulic calculation for pumps involves determining the flow rate, pressure, power, and efficiency of a pump system.
• Calculate flow rate using the formula Q = VA, where Q is flow rate, V is velocity, and A is cross-sectional area.

• Determine pressure using the formula P = F/A, where P is pressure, F is force, and A is area.

• Calculate power using the formula P = Q*H*rho*g, where P is power, Q is flow rate, H is head, rho i...read more

Q2. What are types of pumps?
Ans. 
Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.
• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: trap a fixed amount of fluid and then force it into a discharge pipe.

• Axial flow pumps: move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial flow

Q6. Describe Detailed Pump hydraulic calculation?
Ans. 
Pump hydraulic calculation involves determining the pump head, flow rate, and power requirements for a specific system.
• Calculate total dynamic head (TDH) by adding the static head, friction head, and velocity head

• Determine the required flow rate based on system requirements

• Calculate the pump power requirements using the formula: Power (kW) = (Q x TDH) / (3.6 x efficiency)

• Consider factors such as pump efficiency, pipe s

Q7. What is Coefficient of Control valve?
Ans. 
The coefficient of a control valve is a measure of the valve's flow capacity relative to the pressure drop across it.
• The coefficient of a control valve, also known as the flow coefficient (Cv), is a dimensionless number that represents the flow capacity of the valve for a given pressure drop.

• It is used to compare the performance of different valves and is typically determined experimentally.

• A higher coefficient indicat...read more
