identify the limitations that exist withi different types of water turbines

PROBLEM 1 In an axial flow pump, the rotor has an outer diameter of 75 om and an inner diameter of 40 cm, it rotates at 500 rpm. At the mean blade radius, the inlet blade angle is 12 deg and the outlet blade angle is 15 deg Sketch the corresponding velocity diagrams at inlet and outlet and estimate the following (1) the head the pump will generate, A. 11.2 m B 17 6m C5.4 m D 19 8 m (ii) the discharge or rate of flow in l/s B. 203 s C.407 Us D 609 Vs A 705 Vs (iii) the shaft h.p input required to drive the pump and B 230 hp C:300 hp D 401 hp A 170 hp (V) the specific speed of the pump. B. 65 C.45 D 75 A 80

1) A single-stage centrifugal pump operating at 650 rpm and delivering 250 gallons per second has a specific speed of 4750 rpm. The suction flange is 609.6 mm in diameter and has a vacuum pressure of 70 kPa. The discharge flange is 22 inches in diameter and its centerline is 30.5 cm above the suction centerline. What discharge pressure in kPaa would you expect to find?

Q8- When the pump in Fig. draws 220 m/h of water from the reservoir, the total friction head loss is 5 m. The flow discharges through a nozzle to the atmosphere. Estimate the pump power in kW delivered to the water. D= 12 cm D= Scm Pump Water
