Cooling water is pumped from a reservoir to rock drills on a construction job using the pipe system shown. The flow rate must be 600 gpm and water must leave the spray nozzle at 120 ft/s. Calculate the minimum pressure needed at the pump outlet. Estimate the required power input it the pump efficiency is 70 percent.

Solution

The answer of following given question is as follows .

By applying the bernoullis equation we get the power output is 169.23 HP
