Ten litre of water per second is lifted from well through 20m and delivered with a velocity of 10 m/s, then the power of the motor is :

A motor pump-set lifts 300kg of water per minute from a well of depth 20m and delivers to a height of 20m.Then its power is ?

A motor pump lifts water from an average depth of 15 m at the rate of 5 kg per second. If the water is coming out of the pump with a velocity of 4 ms^(-1) , the power of the motor is (g = 10ms^(-1))

A tube - well pump out 2400 kg of water per minute. If water is coming out with a velocity of 3m/s, the power of the pump is

A tube - well pump out 2400 kg of water per minute. If water is coming out with a velocity of 3m/s, the power of the pump is

A pump is required to lift 1000 kg of water per minute from a well 20 m deep and ejects at a speed of 20 m/s. The power of engine is

A pump is required to lift 1000 kg of water per minute from a well 20 m deep and ejects at a speed of 20 m/s. The power of engine is

An engine pumps water through a hose pipe water passes through the pipe and leaves it with velocity of 2 m/s. The mass per unit length of water in the pipe is 100 kg/m .What is the power of the engine ?

The average power of the pump which lifts 20kg of water per second from a well 10m deep and projects it with a velocity 10m//s is (g=10m//s^(2))
