Assume a 30-cm diameter horizontal pipeline conveys water at a flowrate of 0.21 m³/s. The pressure is 760 kPa but can be reduced to 450 kPa without jeopardizing the water supply (in such an installation, a very small turbine is placed in the water supply pipeline that has "excess" pressure. As the water flows through the turbine, energy is removed. The downstream pipeline pressure is reduced, but it is not lower than that needed by the city's water users). What is the head (m) that is available for the turbine to remove from the flow? If the turbine has an efficiency of 75%, what is the power (W or kW) that can be sold to the local utility?
