A hydroelectric power plant has a dam 100 ft high, and water can flow through the dam and water turbines at 1 million lbm per minute over a 60-ft drop. If the turbines can convert the loss in potential energy of the water into electric power at an efficiency of 70%, how much power can the facility produce in megawatts? (Note: 550 ft ·lbf/s = 1 hp = 0.746 kW)

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...

A hydroelectric power plant has a turbine whose speed must be fixed at 240 rpm. The turbine is impulse type with 12 m diameter. When the flow rate at the nozzle of the penstock is 10 m3/s, the generated electricity is 60 MW. Compute the velocity of the water jet (i.e., Find Vi).

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.

(1) Ideal Rankine A power plant operates using an ideal Rankine cycle. Saturated liquid water enters the pump at P1 = 25 kPa. After being pumped, it passes through the boiler before entering the turbine at P3 = 5 MPa and T3 = 500 °C. If the mass flowrate of the working fluid is m = 20 kg/s, what are Wnet, Oh, and ntn? Draw this on a T-s diagram, labeling the given pressures and temperature as well as arrows...
