20,000 lb/hr of air is to be cooled from 150°F to 100°F by water flowing in a shell-and-tube heat exchanger. Cooling water is available at 70°F and should leave the exchanger at 95°F. Available to do this cooling assignment is a one-shell pass, two-tube pass exchanged consisting of fifty 1-in OD 18 BWG copper tubes, each 10 ft long. The tubes are arranged inside a 10-in shell on a staggered 1-1/4- inch triangular pitch with baffles spaced every 6 in. Is this exchanger satisfactory?
