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

If one pipe A can fill a tank in 20 minutes, then 5 pipes, each of 20% efficiency of A, can fill the tank in :

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 )

A pump on the ground floor of a building can pump water to fill a tank of volume 30m^3 in 15 minutes . If the tank is 40m above the ground and the efficiency of the pump is 30% , how much electric power is consumed by the pump?

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