At the maximum rate of power generation, a small hydroelectric power plant takes a discharge of 16.2 m/s through an elevation drop of 61 m. The head loss through the intakes, penstock, and outlet works is 5.8 m. The turbine, combined with the electrical generator, is able to convert 86% of the mechanical energy into electrical energy. What is the rate of electrical power generation? The water temperature is 15°C. Elevation = 61 m Penstock Powerhouse 4 Elevation = 0...

The vertical drop of water in a hydroelectric power plant is 155m (See figure below). Water flows through the plant and into the lower river at the rate of 425m/s. Assume the overall efficiency of the plant as 80%. Density of water d is equal to 1000kg/m3 Acceleration due to gravity g is equal to 9.81m/s2. Ignore the viscous losses in the flowing water.

a) The following figure shows a water dam built for a hydroelectric power project running constantly round the year. During a dry season, it acts as water reservoir of constant height 80 m. Meanwhile rainy season, water flow of 3 m/s is added to the system. (Water density 10x10 kg/m' and volume flow, V = 45x10 m/s respectively and the gravitational acceleration is about 9.8 kg/m for both seasons).

The following diagram illustrates a simple steam power plant. A
10kg/s flow of liquid water at T1=25°C enters the pump at a
pressure of P1=100kPa and is then pumped to a pressure of P2=2MPa.
The boiler then heats the water at constant pressure to produce
superheated vapour at T3=450°C. The steam is then expanded in the
turbine to a final pressure of P4=100kPa. The turbine and pump are
well insulated and may be considered reversible.
