A typical coal-fired power plant generates 1000 MW of usable power at an overall thermal efficiency of 37%.
Part A
What is the rate of heat input to the plant?
Part B
The plant burns anthracite coal, which has a heat of combustion of 2.65×107J/kg. How much coal does the plant use per day, if it operates continuously?
Part C
At what rate is heat ejected into the cool reservoir, which is the nearby river?
Part D
The river's temperature is 18.0 ∘C before it reaches the power plant and 18.6 ∘C after it has received the plant's waste heat. Calculate the river's flow rate, in cubic meters per second.
Part E
By how much does the river's entropy increase each second?

A typical coal-fired power plant burns 290 metric tons of coal every hour to generate 800 MW of electricity. 1 metric ton= 1000 kg. The density of coal is 1500 kg/m3 and its heat of combustion is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electrical energy. Part A)Suppose the coal is piled up in a 8.0 m × 11 m...

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...
