1. [lpt A power plant produces 48 MW of electric power with an efficiency of 39 %; the waste heat is discharged into 14 ocean water. Suppose the waste heat could instead be used to heat homes during the winter. If a typical Canadian home requires 4 kW on average for heating, how many homes could be heated with the waste heat of this power plant?

A steam-electric power plant delivers 900 MW of electric power. The surplus heat is exhausted into a river with a flow of 4.95×105 kg/s, causing a change in temperature of 1.12 oC. What is the efficiency of the power plant (in % Don't enter a unit.)? Incorrect. What is the rate of the thermal source?

A nuclear power plant has an electrical power output of 1000 MW and operates with an efficiency of 33%. If the excess energy is carried away from the plant by a river with a flow rate of 1.4e6 kg/s, what is the rise in temperature of the flowing water? Hint: Consider the flow of energy during one second. During that second, the power plant does 1000 MJ of work ?. Knowing the work and the efficiency, you can calculate the...

Please show all the algebra steps required to complete the following problem: A nuclear power plant has an electrical power output of 1125 MW and operates with an efficiency of 42%. If excess energy is carried away from the plant by a river with a flow rate of 2.1 × 106 kg/s, what is the rise in temperature of the flowing water?
A typical large coal fired electric power plant produces 1,200MW of electricity by burning fuel with...
A typical large coal fired electric power plant produces 1,200MW of electricity by burning fuel with energy content of 3,000 MW. Three hundred and forty (340) MW are lost as heat up the smokestack leaving the rest to drive a generator to produce electricity. However, the thermal efficiency of the turbine is only 45%. That is 45% of the remaining power goes to drive the generator, and 55% is waste heat that must be removed by cooling water. Assume that...

A coal-fired steam power plant produces 175 MW of electric power. The power plant operates on a Rankine cycle with turbine inlet conditions of 7 MPa and 550oC and a condenser pressure of 15 kPa. The turbine efficiency and pump efficiency are both 0.8. The coal has a heating value (energy released when the fuel is burned) of 29,300 kJ/kg. Assuming that 85 percent of this energy is transferred to the steam in the boiler and that the electric generator...

A nuclear power plant has a reactor that produces heat at the rate of 870 MW. This heat is used to produce 240 MW of mechanical power to drive an electrical generator. (a) At what rate is heat discarded to the environment by this power plant? MW (b) What is the thermal efficiency of the plant? A research group plans to construct an engine that extracts energy from the ocean, using the fact that the water temperature near the surface...

Thermal pollution in wastewater. A 1000-MW coal-fired power plant with an efficiency of 35% uses water from a neighboring stream (with flow of 75 m3/s and 20°C) to carry away waste heat. About 12% of waste heat goes up in the smokestack; the remaining 88% is taken away by cooling water. (a) Calculate the amount of waste heat (inkWorkJ/s) to be removed by cooling water (b) If the cooling water is only allowed to rise in temperature by 11°C, what...

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 320 ∘C. The steam spins a turbine, which produces 1000 MW of electric power, then the steam is condensed and the water is cooled to 25∘C before starting the cycle again. Part A: What is the maximum possible thermal efficiency of the power plant? Part B: Cooling water from a river...
