Document Summary
In a firefighting system, a pipeline with a pump leads to a nozzle as shown on the next page. The reservoir on the left has a water level of 70 ft. and the 3 in diameter jet is at. 80 ft: find the flow rate when the pump develops a head of 80 ft, given that we may express. 2/2g where v6 is the velocity in the 6 the friction head loss in the 6 in diameter pipe as 5v6. 2/2g where v4 is the velocity in in pipe and the head loss in the 4 in diameter pipe as 12v4 the 4 in pipe. Note: the area for the 6 in pipe is a6=0. 196 ft2; the area for the 4 in pipe is. A4=0. 087 ft2; the area for the nozzle is 0. 049 ft2. There are no other losses in the system: find the pressure head at the suction side of the pump.
