A shell-and tube heat exchanger is to be utilized. The cold fluid will enter the exchanger on the shell side at a flow rate of 78 kg s a 35 C and 10 bars, and the hot fluid will enter on the tube side at 130 C and 8 bars. The tubes should be thin-walled with an internal diameter of not less than 1.95 cm and outer diameter not less than 2.8 cm. The maximum length of each tube pass in the heat exchanger cannot be less than 2.2 m. The heat transfer coefficient is given, hin = 98.5 W/m. K. Find a suitable assumption that can make sense for the outlet cold and hot temperatures. Also provide justification for assumptions for the missing values. Use water and ethanol as fluids. Find the Log Mean Temperature Difference. Also mention if its counter current or parallel A shell-and tube heat exchanger is to be utilized.
