The impeller of the centrifugal pump is 350 mm diameter, and the width of the blade passages at outlet is 18 mm. A pump, which runs at 16.6 rev/s, is mounted so that its centre is 2.4 m above the water level in the suction sump. It delivers water to a point 19 m above its centre; the friction loss in the suction pipe is 68 Q² meter and that in the delivery pipe is 650 Q² meter where Q in m3/s is the rate of flow. The blades themselves occupy 5% of the circumference and are backward facing at 35° to the tangent. At inlet, the flow is radial and the radial component of velocity remains unchanged through the impeller. Assuming that 50% of the velocity head of the water leaving the impeller is converted to pressure head in the volute, and that friction and shock losses in the pump, the velocity heads in the suction and delivery pipes are negligible, calculate the following: A) The flow rate, m3/s, of the pump.
