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

3. In a small hydroelectric power station, the turbine uses the energy of the water in the reservoir behind the dam to produce 12000 horsepower. The circular channels before and after the turbine have a diameter of 90 inches. If the head loss across the dam can be calculated from hloss=cV²/2g where c=8 and V is the water velocity in the circular channel, calculate the volumetric flow rate, Q, through the system and the corresponding head loss for h=400 ft...

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)

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...
