Save 27 O Part 1 of 3 Required information A counter-flow heat exchanger is stated to have an overall heat transfer coefficient of 284 Wim when operating at design and clean conditions. Hot fuld enters the tube side at 127C and exits at 7Cwhile cold buid 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 fouting factor of 0.0004 m2 K/W. The surface area is 93 m? Assume both hot and cold fluids have a specific heat of 4.2 kJXOK Т. 10 points Hint seserences Tin Determine the rate of heat transfer in the heat exchanger (Round the answer to two decimal places)
