A. Assume a coal burning power plant generates superheated steam at 1200oC.
The steam expands through a two-stage turbine and is eventually exhausted at 200oC.
Question- What is the maximum theoretical efficiency?
B. Further suppose that this plant produces 40 GJ of heat by burning 1 hour's worth of coal. If the plant is rated at 4 MW of electrical production what is the real efficiency? Recall that a Watt is a Joule per second. (Gigga, G = 109)
