The pump shown below delivers a head of 75 m (hpump) to the water. The total length and the diameter of the pipe are 150 m and 20 cm, respectively. This is a very new and very smooth pipe. There are four 90° threaded regular elbows and one angle valve along the pipe. Determine the power (in kW) that the pump adds to the water. The difference in elevation between the lake and the reservoir is 60 m. Elbow Elbow Reservor Elbow GElbow Vole LAKE

8. Energy Equation Water at the Lake William Dam enters a hydraulic turbine through a 30 cm diameter pipe at a rate of 0.6 m³/s and exits through a 25-cm diameter pipe. For the system, elevation effects are negligible and the pressure drop across the turbine is measured to be 148 kPa. For a combined turbine-generator efficiency of 83 percent, calculate (a) hurbine and (b) Wubrine- You look in the FE handbook and see: W turbine = 7/turbine-gen”ightutine, e turbine-genhtubine, e 30 cm diameter 25 cm diameter Turbine Generator

The 600 mm pipe shown conducts water from reservoir A to a pressure turbine, which discharges through another 600 mm o pipe into tail race B. The head lost from A to 1 is 5 times the velocity head in the pipe and the head lost from 2 to B is 0.2 times the velocity head in in the pipe. If the discharge is 700 L/s A) Compute for the total head lost 1. 05: Compute for the extracted energy cause by the turbine Compute for the hp given up by the turbine.
