ENGR 320 Exam2 Name 1: (15+5 pts) A hydroelectric power plant takes in 25 m's of water through its turbine and discharges it to the atmosphere at V2-I m/s. The head loss in the turbine and penstock system is 10 m. Assuming turbulent flow, a -1.12, (a) What it the power in MW extracted by the turbine? () If the efficiency of the turbine and electrical generator is 85% what is the net power (in MW) generated by this plant?...
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)
Please show your work 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...

In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...
If the required power output of a nuclear plant that has an overall efficiency of 37.3% is 1.05 Gw, determine the amount of nuclear fuel (in kg) consumed each day if the fuel is 222U and each fission reaction produces 200 MeV nuclear fuel (in kg) consumed each day if the fuel is 9 and each fission reaction produces 200 MeV. 1.89823e-8 X Knowing the daily power requirement and efficiency of the plant, how can you determine the needed power...
6. Determine the power required for a 5000-kg car to accelerate from 5m/s to 20m/s in 10 seconds. (Show the formula and procedures.) 7. For a hydroelectric plant, a hydraulic turbine-generator is installed at the site below the free surface. The turbine drives a generator for electricity. The elevation difference between the two free surfaces is h = 60m. The mass flow rate of water is th = 300kg/s. The shaft power output from the turbine is W. = 87kW....
A power plant operates on a regenerative vapor power cycle with one open feedwater heater. Steam enters the first turbine stage at 12 MPa, 560°C and expands to 1 MPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 6 kPa. Saturated liquid exits the open feedwater heater at 1 MPa. The net power output for the...

(b) The daily design load curve of a residential area is given in the table below. The hydropower facility providing the power has an effective head of 15 m and a plant efficiency of 0.85. What is the minimum daily flow (m3/s) that could meet the demand? What is the minimum required storage capacity (within-day storage) to meet the peak load? If the daily flowrate were 320m3/s, what would be the minimum required storage capacity? Would there be some water...
