A centrifugal pump, located above an open water tank, is used to draw water using a suction pipe (8 cm diameter). The pump is to deliver 20oC water at a rate of 0.02m3/s. The pump manufacturer has speci?ed a NPSHR of 3 m. A food process equipment located between the suction and the pump causes a loss of Cf = 15. All other losses may be neglected. Calculate the maximum height the pump can be placed above the water level in the tank without cavitation.
