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.
Problem 6.123 As shown in the figure below, water behind a dam enters an intake pipe at a pressure of 24 psia and velocity of 5 ft/s, flows through a hydraulic turbine-generator, and exits at a point 21 = 140ft below the intake at 19 psia, 45 ft/s, and a specific volume of 0.01602 ft/lb. The diameter of the exit pipe is 5 ft and the local acceleration of gravity is 32.2 ft/s2. Water Dam P1 = 24 psia Vi...
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)
A hydro power station uses Pelton turbine to generate power from a water body behind a dam which has the height of 40 m. (a) Estimate the maximum jet speed to be used to drive the Pelton turbine. (b) The height of the dam water remain constant as a results of a river, with flow rate of 500 m3 s −1 , flowing into the dam reservoir. Estimate the power generating capacity of this river-dam configuration
A dam collects water at a height of 300m. The water can be let down through a pipe. As it falls to the ground it loses potential energy but it gains kinetic energy. 100 tonnes (note 1 tonne 1000 kg) of water are let out from the dam and reach the ground, 300m below; all the gained kinetic energy is then harnessed by a perfectly efficient turbine and converted into energy to power houses in the valley. The Bureau of...
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...
The fresh water behind a reservoir dam is 15.0 m deep. A horizontal pipe 2.50 cm in diameter passes through the dam 7.5 m below the water surface, as shown in the figure. A plug secures the pipe opening. Find the magnitude of the frictional force between plug and pipe wall. The plug is removed. What volume of water flows out of the pipe in 2.0 hours?
water 248 m 945 ml 2 Water Pipe GENERATOR TURBINE 1) A dam in somewhere with a height of 248 m, is one of the tallest dam in the world. Water flows with a volumetric flow rate of 65 m'ls to a turbine, where electric power is generated. The total irreversible head los in the piping system from point 1 to point 2 (excluding the turbine unit) is determined to be 95 m. The pressure difference due to elevation cannot...
