    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). Evaluate the followings: Ravet afsec RE Figure 2: Water flow utilization...

    25. In a hydroelectric dam, water falls 25 m and then spins a turbine to generate electricity. a) What is U, of 1.0 kg of water? b) Suppose the dam is 80% efficient at converting the water's potential energy to electrical energy. How many kilograms of water must pass through the turbines each second to generate 50 MW of electricity? This is a typical value for a small hydroelectric dam.

    9) Electrical power is to be generated by installing a hydraulic turbine-generator at a site 70 m below the free surface of a large water reservoir that can supply water at a rate of 1500 kg/s steadily. If the mechanical power output of the turbine is 800 kW and the electric power generation is 350 kW, determine the turbine efficiency and the combined turbine-generator efficiency of this plant. Neglect losses in the pipes. (10pts).

    1. The Davis Dam was constructed 67 miles downstream from the Hoover Dam. The reservoir formed by the dam is called Lake Mohave. The reservoir has a total storage capacity of 1,818,300 acre-feet. Given the average head of the reservoir is 136 feet, determine the potential energy of the water in the reservoir. 2. When the effective head of water behind the Davis Dam is 41 meters, a penstock 22 feet in diameter will flow 42,000 gallons of water per...

    The state of Iowa is among the top three states in U.S. in wind power generation. In 2016, over 20 billion kWh of electrical energy in Iowa was generated by wind power. Assuming that wind speed at the altitude of wind turbine is in average of 6 m/s, the efficiency of converting wind energy to the electricity is 80 %, and all wind turbines work constantly throughout the year. We can further assume that the air in Iowa has an...
