Water (p 1000 kgm3) is pumped through a smooth 2 inch diameter pipe, 50 m higher than the pump intake into the top of a tank at atmospheric pressure. the water pressure before the pump is 300 kpa (absolute). water leaks at the base of the tank through a sharp-edged orifice of diameter 1 inch with a discharge coefficient of 0.7. if the head loss through the pipes is 2.1 m, how much energy must the pump supply to maintain the level in the tank at 3 m above the orifice?
