2. A centrifugal pump having extermal and intemal diamcters as 750 mm and 400 mm respectively is operating at 1000 r.p.m. The vancs are curved hack at 35° to the tangent at outlet. If the velocity of flow is constant at 6 m/s, find (a) vane angle at inlet, and (b) work done per kN of water. (Ans. 16°; 123 kJ)
