Water is pumped out of a well 10m deep by means of a pump rated at 10 kW. Find the efficiency of the motor if 4200 kg of water is pumped out every minute. Take `g = 10m//s^2.`

Water is pumped out of a well 10 m deep by means of a pump rated 10 KW. Find the efficiency of the motor if 4200 kg of water is pumped out every minute. " Take" g = 10 m/s2

Water is pumped out of a well 10 m deep by mean of a pump rated at 10 kW . Find the efficient of the motor if 4200 kg of water is pumped out every minutes . Take g=10 ms ^(-2) .

A motor of power 10 kW is used to pump water from a well 20 m deep . Calculate the efficiency of the motor if it pumps 200 kg of water every minute . Take g = 10 m//s^(2)

A pump of power 20 kW is used to jump out the water from a well 12 m deep . Calculate the efficiency of the pump if 5,000 kg of water is pumped out in 1 minute .

A pump on the ground floor of a building can pump up water to fill a tank of volume 30 m^3 in 15 min. If the tank is 60 m above the ground, and the efficiency of the pump is 40%, how much electric power is consumed by the pump? (Take g = 10 m s^(-2) )

A 750 W motor drivers a pump which lifts 300 litres of water per minute to a height of 6 meters. The efficiency of the motor is nearly (take acceleration due to gravity to be 10 m//s^(2))
