Chemvap Engineering Private Limited Interview Questions, Process, and Tips

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

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

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
