Power Of A Water Draing Pump

Water is being pumped out through a circular pipe whose internal diameter is 7 cm. If the flow of water is 72 cm per second, how many litres of water are being pumped out in one hour?

The power of a water pump is 2 kW. If g = 10 m//s^2, the amount of water it can raise in 1 min to a height of 10 m is :

The water for a factory is stored in a hemispherical tank whose internal diameter is 14 m. The tank contains 50 kL of water. Water is pumped into the tank to fill to its capacity. Calculate the volume of water pumped into the tank.

Water is being pumped out through a circular pipe whose internal diameter is 7cm. If the flow of water is 12 cm^3 per second, how many litres of water is being pumped out in one hour ?

The power of water pump is 4 kW. If g=10 ms^(-2), the amount of water it can raise in 1 minute to a height of 20 m is

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) )

What is the power of a pump which takes 10 seconds to lift 100 kg of water to a water tank situated at a height of 20 m? ( g = 10 m s^(-2) )
