A centrifugal pump was purchased to pump the water from an open tank to a water jet spray cleaner. The spray cleaner requires a pressure of 75 kN/m2 (gauge pressure). The hose that connects the tank to the pump and to the spray jet is 25 m long and has an internal diameter of ¼ inch (0.64 cm). The hose also has a small “kink” in the line that adds some extra head loss with an approximate head loss coefficient of Kkink = 0.3. The spray jet nozzle is located 15 m above the tank liquid surface. Assuming a frictional loss of 0.002 in the line, determine the flow rate and head of the pump. Assume that the spray nozzle has the same diameter as that of the hose and α=1. The centrifugal pump was tested by the supplier before delivery and the performance data is provided in the table below.
