A propane / propylene mixture consists of 95% propane that has a flow rate of 1.31083 kg/s is initially at 54.44 °C. By inserting it in the shell side of a cross-flow shell and tube heat exchanger with one fluid unmixed. The heat exchanger has two shell passes. There are 3020 tubes each one has a diameter of 1.905 cm and 5.6388 m long, contains quenched water at a flow rate of 3.402 kg/s with an inlet temperature of 85 °C. The overall heat transfer coefficient “U” is equal to 8.5637 w/m^2 * c
Consider Cpc = 3.2387 J/kg*C , and Cph = 4.2 J/kg*C. (Assume the mixture has properties of propane). Calculate:
1- T out hot
2- T out cold
3- q
Use a solver with LMTD method (computer code in Matlab, or if you don’t know you can use Excel.). First, set your equations and assumptions and then use the solver.
