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...

Question 4 (2+3) The Hoover dam is a huge hydroelectric power plant in the desert close to Las Vegas. It creates power by converting the potential energy of water at a height into electrical energy. The power available for generating electricity is given by: P = pQgh, with p = 997 kg/mthe density of water, Q the flow rate of the water (in m3/s), g the gravitational constant and h = 221 m the height of...

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...

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.

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...

A pumped-storage hydroelectric plant generates high value electricity during peak demand times, by allowing water (density 1,000 kg/m3) to run through a pipe from an elevated reservoir through a bank of turbines and then into a lower level reservoir. It then uses low-cost, off-peak electricity to pump the water back up into the upper reservoir The water surface in the very large upper reservoir (A) is 600 m above datum whilst that in the very large lower reservoir (B) is...
