Ammonia is used in a system that produces chilled water. Ammonia at 4°C must be heated to at least 40°C using steam. The steam is a saturated vapor at 15 kPa and should leave the exchanger as a saturated liquid. The steam flow rate is variable. Size a heat exchanger for this task and take into account fouling effects. What is the required steam flow rate when the exchanger is new, and what is it after 1 year has passed? The ammonia flow rate is 150 000 kg/hr.
