A large coal-fired power plant is outputting 1333 MW of electrical power. Its thermal efficiency is 32%. It is burning coal with an energy content of 11000 BTU/lb. A train car carries approximately 100 tons of coal.

(a) How many coal cars per day does this power plant require?

(b) A train car occupies approximately 4000 cuft of volume. What is the volume of coal burned per day at the above power plant?

(c) Typical house has volume of approximately 20000 cu ft. How many houses full of coal would this volume of coal fill?

(d) If the coal is pure carbon, how much CO2 in tonnes/year would this power plant produce? At 298K and 1 atmosphere, how many Pentagon sized office buildings would this occupy?
