Formula Used
Efficiency of Jet Pump = (Discharge through Suction Pipe*(Suction Head+Delivery Head))/(Discharge through Nozzle*(Pressure Head on Delivery Side-Delivery Head))
η = (Qs*(hs+hd))/(Qn*(H-hd))
This formula uses 6 Variables
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.
STEP 1: Convert Input(s) to Base Unit
Discharge through Suction Pipe: 11 Cubic Meter per Second --> 11 Cubic Meter per Second No Conversion Required
Suction Head: 7 Meter --> 7 Meter No Conversion Required
Delivery Head: 4.01 Meter --> 4.01 Meter No Conversion Required
Discharge through Nozzle: 6 Cubic Meter per Second --> 6 Cubic Meter per Second No Conversion Required
Pressure Head on Delivery Side: 46 Meter --> 46 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
η = (Qs*(hs+hd))/(Qn*(H-hd)) --> (11*(7+4.01))/(6*(46-4.01))
Evaluating ... ...
η = 0.480709692783996
STEP 3: Convert Result to Output's Unit
0.480709692783996 --> No Conversion Required
FINAL ANSWER
0.480709692783996 0.48071 <-- Efficiency of Jet Pump

What is a jet pump?

A jet pump consists of a conventional radial flow pump with jet nozzle at the suction end. It helps to increase the suction lift beyond the normal limit of about 8 metres of water head. With the use of jet assembly it is possible to increase the suction lift upto 60 m.

How to Calculate Efficiency of Jet Pump?

Efficiency of Jet Pump calculator uses Efficiency of Jet Pump = (Discharge through Suction Pipe*(Suction Head+Delivery Head))/(Discharge through Nozzle*(Pressure Head on Delivery Side-Delivery Head)) to calculate the Efficiency of Jet Pump, Efficiency of Jet Pump formula is defined as the ratio of the output power of the pump to the input power, which represents the effectiveness of the jet pump in converting the energy supplied to it into useful work. Efficiency of Jet Pump is denoted by η symbol.
