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))`

A pump can raise 100 L of water per minute to a height of 10 m . What should be the power of the pump ?

A pump lifts 5000kg of water per minute through a height of 12m. Find the power of the engine if 30 % of energy is wasted.

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 pump lifts 373 kg of water to a height of 10m in 98s. Find the power of the pump. Express it in horsepower.

The power of motor pump is 2 KW. The water raised by the pump per minute to a height of 10 m. is nearly :

A motor which is capable of raising 2,000 litres of water in 3 mins from a well 120 m deep. So what is the power of a motor ?

Find the total energy of a body of 5 kg mass , which is at a height of 10 m from the earth and falling downwards straightly with a velocity of 20 m/s (Take the acceleration due to gravity as 10m//s^(2) )
