5) Heat exchanger is used to heat petroleum distillate for use in a chemical process. Hot water enters the unit at 210oF and leaves at 120oF. If the specific heat of water is taken to be 1.0 Btu/Ibm.oR and the distillate has a specific heat of 0.82 Btu/Ibm.oR, and the masses of water and distillate are 5 Ibm and 3 Ibm, determine the temperature at which the dilate leaves if it enters at 85oF.

Hot air enters a heat exchanger at 350°C and exits at (149°C. The heat extracted is used to boil (0.263) kg/s of 100°C water (from saturated liquid to saturated steam). The heat exchanger is a single-shell shell-and-tube heat exchanger with two tube passes. The overall heat transfer coefficient for the hot side is 240 W/(m2°C). Assume a constant specific heat for air of Cp = 1.005 kJ/(kgC). The pressure of the hot air and the boiling water is P =...
