An electrical power plant has an overall efficiency of 15%. The plant is delivered 150MW of power to a city, and turbines use coal as fuel. The burning coal produces steam at 190 0C, which drives the turbines. The steam is then condensed at 25 0C by passing it through cooling coils in contact with river water. a) How many metric tons of coal does the plant consume each day? b) What is the total cost of the fuel per year if the delivered price 10 USD per metric ton? c) If the river water is delivered at 20 0C, at what minimum rate must it flow over the cooling coils in order to that its temperature not exceeds 25 0C? Heat of combustion of coal is 33 kJ/g

Question
An electrical power plant has an overall efficiency of 15%. The plant is delivered 150MW of
power to a city, and turbines use coal as fuel. The burning coal produces steam at 190 0C,
which drives the turbines. The steam is then condensed at 25 0C by passing it through cooling
coils in contact with river water.
a) How many metric tons of coal does the plant consume each day?
b) What is the total cost of the fuel per year if the delivered price 10 USD per metric
ton?
c) If the river water is delivered at 20 0C, at what minimum rate must it flow over
the cooling coils in order to that its temperature not exceeds 25 0C? Heat of
combustion of coal is 33 kJ/g
