Discharge (Q) of a centrifugal pump is given by (where D = Diameter of impeller at inlet, b = Width of impeller at inlet and Vf = Velocity of flow at inlet)
A. $${\text{Q}} = \pi {\text{D}}{{\text{V}}_{\text{f}}}$$
B. $${\text{Q}} = \pi {\text{b}}{{\text{V}}_{\text{f}}}$$
C. $${\text{Q}} = \pi {\text{Db}}{{\text{V}}_{\text{f}}}$$
D. $${\text{Q}} = {\text{Db}}{{\text{V}}_{\text{f}}}$$
