Preliminary cost estimates for a 1 million-Kw nuclear-powered thermal power station require an estimate of the cooling water demands of the facility. For purposes of this estimate, the heat engine can be assumed to be a carnot engine operating between 650 F Degree and 150 F Degree. If cooling water enters the process and saturate liquid at 70 F Degree and leaves as saturated liquid at 120 F Degree, at what rate (gallon per minute) must cooling water be supplied?
