An electric pump on the ground floor of a building taken 10 minute to fill a tank of `45m^3` with water. The tank is `20 m` above the water level . If electric power consumed by the pump is `30kW` then efficiency of the pump will be ( density of water is `1000 kg/m^3`)

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) )

An electric pump is used to pump water to fill a water tank of volume 30 m^(3) is 20 minute. The pump is on the ground floor and the tank is on the terrace of the builiding. The centre of the tank is at 40 m above the ground . How much electric power is consumed by the pump, in filing the tank , if the efficiecy of the pump is 50 ? ( g = 10 m//s^(2) and density of water 10 = ^(3) kg //m^(3) )

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

A tank on the roof of a 20 m high building can hold 10 m^(3) of water. The tank is to be filled form a pond on the ground in 20 minutes. If the pump has an efficiency of 60 % , then the input power in kW is

An electric pump is used to fill an overhead tank of capacity 9m3 kept at a height of 10 m above the ground. If the pump takes 5 min to fill the tank by consuming 10 kW power, the efficiency of the pump should be

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 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
