You are required to size a shell and tube heat exchanger to cool 100,000 kg/hr of n-heptane at a pressure of 2 bar.g from 95C to 40C before specifying the tube sheet thickness using PD5500. All parts of the unit will be constructed of carbon steel with tensile and yield stresses of 310 N mm and 165 N mm, respectively and a Young's modulus of 200 GPa. A corrosion allowance of 2 mm should be employed on the tube sheet. Brackish water will be used as the cooling medium and a maximum outlet temperature of the cooling water of 40C is permitted. The cooling water inlet pressure will be 2 bar.g.
