Heat-Exchangers-and-Mass-Transfer

Exhaust gases (c P = 1.12 k J/kg K) flowing through a tubular heat exchanger at rate of 1200 kg/hr are cooled from 400 degree Celsius to 120 degree Celsius. This cooling is affected by water (c P = 4.18 k J/kg K) that enters system at 10 degree Celsius at rate of 1500 kg/hr. If overall heat transfer coefficient is 500 k J/m2 hr degree, what heat exchanger area is required to handle load for parallel flow arrangement?

In a food processing plant, a brine solution is heated from – 12 degree Celsius to – 65 degree Celsius in a double pipe parallel flow heat exchanger by water entering at 35 degree Celsius and leaving at 20.5 degree Celsius. Let the rate of flow is 9 kg/min. Estimate the area of heat exchanger for an overall heat transfer coefficient of 860 W/m2 K. For water c P = 4.186 * 10 3 J/kg K
