Variables Used
Efficiency of Jet Pump - Efficiency of jet pump is denoted by η symbol.
Discharge through Suction Pipe - (Measured in Cubic Meter per Second) - The discharge through suction pipe refers to the movement or withdrawal of fluids via suction, creating a vacuum to draw liquids or gases into a system, commonly used in pumps, vacuum systems.
Suction Head - (Measured in Meter) - Suction Head is the vertical height of the center line of the pump shaft.
Delivery Head - (Measured in Meter) - Delivery Head is vertical height of the liquid surface in the tank/reservoir to which the liquid is delivered.
Discharge through Nozzle - (Measured in Cubic Meter per Second) - The discharge through nozzle involves the controlled flow or release of fluid or gas at high velocity and pressure.
Pressure Head on Delivery Side - (Measured in Meter) - Pressure Head on Delivery Side refers to the pressure energy or head possessed by a fluid at a specific point in a fluid system, specifically on the delivery side of a system.
