Saturated steam at 373 K is to be condensed in a shell- and-tube exchanger; it is to enter as steam at 373 K and leave as condensate at approximately 373 K. If the NTU rating for the condenser is given by the manufacturer as 1.25 in. this service for a circulating water flow of 0.07 kg/s, and circulating water is available at 280 K, what will be the approximate maximum flow rate of steam in kg/s that can be condensed? What will be the leaving temperature of the circulating water under these conditions? Under these conditions, the heat vaporization is 2257 kJ/kg, and c_p, is 4.18 kJ/kg · K.
