Question
A Pelton wheel develops 70 kW under a head of 60 m of water. It rotates 400 rpm. Overall efficiency is 80%. Find the discharge rate in m³/s. Use the equation below, where P is power of the turbine shaft and no is the overall efficiency, where specific weight of water is is 9.80 kN/m³ no P YQH A generator is driven by a small, single-jet Pelton turbine designed to have a power specific speed sp 0.20. The effective head at nozzle inlet is 200 m and the nozzle velocity coefficient is 0.985. The runner rotates at 880 rev/min, The turbine overall efficiency is 80%. Find (a) the power delivered by the shaft of the turbine and (b) find the power delivered by the water to the turbine. where density of water is 1000 kg/m³ and g is 9.80 m/s². Use Stup Ω P/p (gHE)* Overall efficiency ne and Power developed at turbine shaft hydraulic power P YQH
