1. A centrifugal pump with 30 cm impeller delivers 30 l/s against a head of 24 m when running at 1750 rpm. What will be the delivery of a homologous pump of 15 cm impeller diam eter assuming same efficiencies and speed?
2. A centrifugal pump with 2.3 diameter impeller running at 327 rpm delivers 7.9 m3/s of water.
The head developed is 72.8 m. The width of the impeller at outlet is 0.22 m. If the overall
efficiency is 91.7% determine the power to drive the pump.
29Water enters the impeller of a centrifugal pump radially at a flow rate of 250 L/min. The rotational speed of the impeller shaft is given as 400 rpm. Since the outer diameter of the impeller is 60 cm and the tangential component of the output velocity at this point is 55 m/s, calculate the torque (Nm) coming to the impeller.
A centrifugal blower rotates at 1400 rpm. Air enters the impeller normal to the blades (?1 = 0°) and exits at an angle of 25° (?2 = 25°). The inlet radius is r1 = 6.5 cm, and the inlet blade width b1 = 8.5 cm. The outlet radius and blade width are r2 = 12 cm and b2 = 4.5 cm, respectively. The volume flow rate is 0.22 m3 /s.
