Ôf a gal pump is 300 mm neter and 50 mm wide at the periphery. The angle made by the blade at the tip with the forward direction of the impeller is 30 degrees. See figure. The pump delivers 0.2 m²/s and the impeller rotates at 1000 rpm. 1. Calculate the speed and direction of the water as it leaves the impeller. 2. If the pump is designed to admit water radially, calculate the torque exerted by the impeller on the water. 3. Determine the shaft power required for the pump assuming an efficiency of 70%. 4. Determine the equation of the pump curve. 30° D = 300mm
