A water pump lifts water at the rate of 5 litre per second through an average height of 8 m from a well of depth 12 m. Its power will be :-

A motor pumps water at the rate of V m^(3) per second, against a pressure P Nm^(-2) . The power fo the motor is watt 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))

An installation consisting of an electric motor driving a water pump left 75 L of water per second to a height of 4.7 m . If the motor consumes a power of 5 k W , then efficiency of the installation is

An installation consisting of an electric motor driving a water pump left 75 L of water per second to a height of 4.7 m . If the motor consumes a power of 5 k W , then efficiency of the installation is

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 :

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 water pump raises water at a rate of 0.50 m^3// min from a depth of 30 m . If the pump is 70% efficient . What power is developed by the engine . g=9.8 m*s^(-2) and density of water = 10^3 kg *m^(-3) .
