A typical coal-fired power plant generates 1000 MW of usable power at an overall thermal efficiency of
Question:
(a) What is the rate of heat input to the plant?
(b) The plant bums anthracite coal, which has a heat of combustion of 265 X 107 J/kg. How much coal does the plant use per day, if it operates continuously?
(c) At what rate is heat ejected into the cool reservoir, which is the nearby river?
(d) The river's temperature is 18.0oC before it reaches the power plant and 18.5oC after it has received the plant's waste heat. Calculate the river's flow rate, in cubic meters per second.
(e) By how much does the river's entropy increase each second?
