A process stream, with an inlet temperature of 110C is to be cooled to 48C. The process stream has a flowrate of 33000kg/h. Cooling water is available at 25C for cooling purposes. The cooling water outlet temperature should not exceed 36C. The physical properties of the process and cooling water stream are as follows: Tubes (k=45Wm1K1) with an outside diameter (OD)=19.05mm, wall thickness of 2mm and length =4.88m, are available. A triangular pitch of 1.25OD has been selected. 1.1 Would you agree that the cooling water stream should be allocated to the tube-side of the exchanger? Justify your answer. (2) 1.2 Decide whether a 1 shell 2 tube pass heat exchanger will be suitable, and then calculate the heat transfer area required for the heat exchanger, based on an overall heat transfer coefficient of 650W/m2K. (9) 1.3 Select the type of exchanger (i.e. fixed-tube, split-ring floating head, pull-through floating head) and calculate the shell bundle clearance and the shell diameter required for the given service. (8) 1.4 Calculate the tube-side heat transfer coefficient. (10) 1.5 Calculate the shell-side heat transfer coefficient using a baffle spacing 0.4 shell diameter. (11) 1.6 Determine the overall heat transfer coefficient and determine the percentage over-design or under-design. 1.8 Calculate the pressure drop on both the tube side and shell side of the heat exchanger and specify whether these are within the limits
