Water at 10°C flows from a large hydroelectric plant reservoir through a cast iron pipe with an internal diameter of 750 mm to a generating unit and is returned to the normal course of the river, downstream, at an elevation 30 m below that of the surface of the hydroelectric reservoir. The turbined flow is equal to 2.5 m3/s. Assume that the pipe has a total length of 70 m. Determine the power in the generator considering an overall efficiency (turbine-generator) of 80%. For this, it is necessary to use the calculation of the pressure drop in the pipe. Assume that the total pressure drop located throughout the system is 20% of the value obtained for the pressure drop distributed in the pipeline.
