A 10 H.P. motor pumps out water from a well of depth 20 m and fills a water tank of volume 22380 litres at a height of 10 m from the ground. The running time of the motor to fill the empty water tank is (`g=10ms^(-2)`)

A 1-KW motor pumps out water from a well 10m deep. Calculate the quantity of water pumped out per second.

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 ?

Suggest a method to fill water in a tank constructed at a height of 10 m from the ground by using a vacuum pump instead of an electric pump.

A motor pump lifts 6 tonnes of water from a height of 25 m to a height 35m from the ground floor in 20 seconds. The power of the pump (in kW) is [g = 10 ms^(-2)]

The level of water in a tank is 5m high.A hole of area 1cm^2 is made in the bottom of the tank. The rate of leakage of water from the hole is (g=10ms^(-2)

Calculate the electric energy consumed by a 2 HP pump if it is used for 2 hours. If the group is used to fill an overhead tank, which is at a mean height of 10 m , find the quantity of water lifted by the pump. (Take g = 10 ms^(-2) ).

An electric pump is used to pump water to fill a water tank of volume 30m^(3) in 20 minute. The pump is on the ground floor and the tank is one the terrace of the building. The centre of the tank is at 400 m above the ground. How much electric power is consumed by the pump, in filling the tank, if the efficiency of the pump is 50%? (g=10m//s^(2) and density of water =10^(3)kg//m^(3) )
