The energy transfer device which is used for lifting water from a well by utilizing the compressed air is known as
A jet pump is located at 3 m above the sump water level and has a head of 13 m applied at the nozzle. If the delivery head is 11 m when the discharge through the pump is 15 L/s and jet discharge is 2.5 L/s, what is the efficiency of jet pump?
An accumulator has a ram of 250 mm in diameter. The effective stroke of the ram is 3 m and the total load on the ram is 300 kN. The frictional effects in the accumulator can be taken as 2% of the total load on the ram. What is the total power delivered by the accumulator when ram falls through its full stroke in 49 seconds?
