Question:
Water at 50°F is available for cooling at a rate of 400 Ibm/h. It enters a double-pipe heat exchanger with a total area of 18 ft2. Oil, with cp = 0.45 Btu/1bm, °F, enters the exchanger at 250°F. The exiting water temperature is limited at 212°F, and the oil must leave the exchanger at no more than 160°F. Given the value of U = 60 Btu/h ft2 °F, find the maximum flow of oil that may be cooled with this unit.
