Chapter 4, Problem 2P(choose chapter or problem)
At a power plant that produces 1 GW (\(10^{9}\) watts) of electricity, the steam turbines take in steam at a temperature of 500°C, and the waste heat is expelled into the environment at 20° C.
(a) What is the maximum possible efficiency of this plant?
(b)Suppose you develop a new material for making pipes and turbines, which allows the maximum steam temperature to be raised to 600°C. Roughly how much money can you make in a year by installing your improved hardware, if you sell the additional electricity for 5 cents per kilowatt-hour? (Assume that the amount of fuel consumed at the plant is unchanged.)

ANSWER:Step 1 of 4
In simplified form, a power plant is defined as the system that takes energy in some other form and converts it into the desired or required form. For example Coal plant takes energy as a chemical process and burns it to convert water into the steam which is used to run the turbine to generate electricity.
