1. A Pelton wheel performance data are collected in the following table. Water supply line pressure (bar) 1 Water flow rate (L/min) 18.4 Turbine speed (RPM) 3000 Shaft torque (Nem) 2.4 If water supply pipe diameter is 25 mm and turbine wheel diameter is 70 mm, calculat the hydraulic head in m, jet velocity in m/s, speed ratio, hydraulic power in W mechanical power in W and efficiency of the turbine. What is the optimum speed (RPM of the wheel (for maximum power)? [8+2+4+3+3+2+6 points] 2. A gear pump performance data are shown in the following table for the oil o Specific Gravity 0.9. Specific weight of Mercury = 847 lb/ft?, 1 ft? = 7.48 gallons, 1 hp = 550 ft.1b/s RPM Suction pressure Discharge pressure Time in seconds for Shaft torque (inch Hg) (psi) 1 gal of flow (lb.in) 200 -12.5 50 44 21 culate pump head in ft, shaft power in hp, fluid power in hp, friction power loss and np efficiency.
