A Centrifugal pump discharges water with a volume flow rate of 110 liters per second. The inlet diameter D1 of the impeller is 150 mm, the blade thickness at the inlet is h-60 mm. Assume that the flow angle at the inlet of the impeller is 90 degree, calculate absolute velocity C1. • a. C1=3.93 m/s b. Cr1=10.3 m/s c. Cr1=5.93 m/s d. None of them are correct e. It is not possible to calculate C1. Because the tangential velocity of the impeller is not given.
