Question

5) The turbine in the figure is used in a small hydroelectric power plant with a 0.3 m diameter pipe. a) If the discharge at point B is 1.7 m³/sec, calculate the amount of power transferred from the water (1000 kg/m³) to the turbine blades (10p). b) If the friction loss in the pipe-turbine line is 4 m, calculate the power loss due to friction (10p). c) Calculate the minimum power of the engine if the friction loss is covered by an engine operating at a maximum mechanical efficiency of 75% (5p).

Step 1

Let's define point A as the free surface of the water in the reservoir and point B as the discharge point after the turbine. Given data: - Diameter of the pipe, D = 0.3 m - Discharge at point B, Q = 1.7 m³/s - Density of water, ρ = 1000 kg/m³ - Height of the Show more…
