1.) A Pelton wheel with a needle-controlled nozzle develops 1 050 kW against a gross head of 300 m. The loss of head due to friction in the pipeline and the nozzle is 60 xV. where is the flow rate in m³/s. Assuming that the overall efficiency of the wheel remains constant at 83%, determine the percentage reduction in flow rate required when the power developed is reduced to 710 kW by closing a valve on the pipeline partially
