To estimate the optimum number of vanes and the blade angle of the centrifugal pump having the following dimensions (see reference [15] for the design of main dimensions). Di -5.8 cm; Di = 20.8 cm; h = 2.2 cm; b 2 = 0.7 cm; iV = 2880 rpm; H = 42 M; Q = 10.43 lps; X = 0.05. Equation (25) reduces to (assuming volumetric efficiency of 95.6) = Z 0.0109 1.39 (, 35 + 2.36 (28) :.8; n -{x -,T. 2 )2810 when x = 0.7925, m = 4.8, and n = -462 Equation (18) results in Z = 6.61 ~ 7 The value of x = 0.7925,
