Power Of A Water Draing Pump

A water pump lifts water from a level 10 m below the ground. Water is pumped at a rate of 30 kg /minute with negligible velocity.Caculate the minimum horsepower the engine should have to do this.

The diameter of the top of a firebrigade pump is 5 cm. Water is thrown by this pump at a horizontal speed of 18 m/s on a wall. If water rebounds back from the wall, then the force exerted by water on wall will be :-

If the power of the motor of a water pump is 3kW , then the volume of water in llitres that can be lifted to a height of 10 m in one minute by the pump is (g = 10 ms^(-2))

A piece of wood is floating in water kept in a bottle. The bottle is connected to an air pump. Neglect the compressibility of water. When more air is pushed into the bottle from the pump, the piece of wood will float with
