The head-discharge relationship for a certain pump can be represented by the equation H = 28 - 9
 • The pump is fixed 2.5 m above the water surface in a river and it forces the water to a level 7 .8 m above the pump. The suction and delivery pipes are 16 m and 764 m long, respectively, and each pipe is 0.8 m in diameter. The pipe coefficient of friction is 0.005. Estimate the time required to lift 1500 tons of water from the river by using this pump. Draw the hydraulic grade line and the total energy line for the pumping system.
