Which type of power plant uses the energy of moving water in nature to generate electricity?
hydro-electric power plants use falling water to generate electricity. Does a typical waterfall generate enough energy to power a light-bulb? Make the appropriate approximations in terms of heigh and amount of water falling down.
A nuclear power plant converts energy from nuclear fission into electricity with an efficiency of 36.0%. How much mass (in kg) is destroyed in one year to produce a continuous 1420 MW of electric power? _________kg
4. How much water is needed to produce 1 kWh of electricity at a power plant that is 30% efficient if the temperature of the water is allowed to increase by 10 degree C ? {please consider that the water is used to for cooling, cooling the waste heat}
1: A privately owned power plant generates electricity. It uses coal, labor and capital as inputs and produces air pollution in the form of particulate matter (PM) and greenhouse gases. PM causes local health problem while greenhouses gases contribute to global climate change. All inputs as well as the air pollution and climate change are associated with costs. Which of these costs does the power plant take into account? How do you call the different type of costs? 2: Which...
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
The water in a large lake is to be used to generate electricity by the installation of a hydraulic turbine generator at a location where the depth of the water is 50 m. Water is to be supplied at a rate of 5000 kg/s. If the electric power generated is measured to be 1862 kW and the generator efficiency is 95 percent, determine (a) the overall efficiency of the turbine-generator, (b) the mechanical efficiency of the turbine, and (c) the...
An electrical power station uses 1.38 × 1014 J of thermal energy input and produces electricity with an efficiency of 42.7% (a) How much electrical energy is produced? (b) How much waste energy is produced by the station? HINT: The waste energy is the thermal energy that doesn't result in the production of electricity. (c) What is the ratio of waste energy electrical energy output? waste energy output energy Please pause for a few seconds to think about whether it's...
A power plant operates on the Rankine cycle and uses a nuclear reactor to generate the steam that enters the turbine. The condenser receives cooling water from a chiller and discharges the used water to a nearby lake. Kinetic and potential effects are negligible. Stray heat transfer from the turbine, pump, and condenser can be neglected. Data are provided in the table for the system operating at steady state.
a power plant has 4 smaller substations. the main power plant generates 420 MW of electricity and is distributed to these substations using high voltage power lines. Each line carries 140 kV while having .20 Ohms resistance in each line. what is the power loss in each transmission line? let the power be distributed equally betewen the 4 substations. 12000 kW 2000 kW 900 kW 4000 kW 450 kW 110 kW
