CH_11_HW_Set Sevec 29 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 excits at 7C, while cold fluid 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 fluids have a specific heat of 4.2 kg K TO Part 3 of 3 10 pos Skipped Tun Bode Jeferences TEMA Calculate the mass flow rate of the cold huid if the rate of heat transfer in the heat exchanger is 135-105 W. Round the answer to a single decimal place) The mass flow rate of the cold fluid is kg
