An electrical generating plant is intended to produce 200 megawatts from coal. Presuming the plant operates at 38% efficiency as well as that coal has a heat content of 30 kJ/g
a. Compute how many tons of coal is used per year
b. If the cooling water absorbs 65% of heat radiated to the surroundings and can raise in temperature no more than 5 oC, Explain what must be the flow of cooling water in m3/sec?
