Cooling water is used to condense propane vapor that enters the condenser saturated at 200 psia. The condensate is a saturated liquid at the same pressure. The cooling water enters the condenser at 70°F and its temperature cannot increase more than 25°F as it passes through the condenser. If the maximum flow rate of the cooling water is 60,000 lbm/h and its heat capacity is constant at 1 Btu/(lbm·°F), estimate the maximum flow rate of propane (SCFH) vapor to the condenser.
