O Required information A counter-flow heat exchanger is stated to have an overall heat transfer coefficient of 284 W/m2K when operating at design and clean conditions. Hot fluid enters the tube side at 127C and exits at 7rc. while cold fuld enters the shell side at 27C and exits at 55°C. After a period of use, built-up scale in the heat exchanger gives a fouling factor of 0.0004 m2 K/W. The surface area is 93 m2. Assume both hot and cold fulds have a specific heat of 4.2 kJ/kg Tess Tin, Tran Determine the rate of heat transfer in the heat exchanger (Round the answer to two decimal places.) The rate of heat transfer in the heat exchanger is 7-106 W. 10 20 100 Next >
