A centrifugal pump discharge 7500 L of water per minute against a total head of 25 m when running at 660 rpm. The outlet diameter of the impeller is 600 mm and the ratio of outer to inner diameter is 2. The area of flow through the wheel is 0.06 m^2. The vanes are set back at an angle of 45 degrees. Water enters the wheel radially and without shock. Calculate (i) manometric efficiency and (ii) vane angle at the inlet.
