Q 5. 150 mol/s toluene is preheated from 25 to 130oC at atmospheric pressure before entering the reactor. The preheating energy is provided by a heat exchanger operating with 8 kg/s inlet superheated steam at 10 bar and 400oC. Assuming that there are no heat loss and no pressure drop across the heat exchanger and no work from either shaft or flow;

I. Draw and label a process flowchart. [1 Mark]

II. Calculate the rate of heat transfer from the water to the toluene. [5 Marks]

III. Analyse the phase of toluene as well as the steam in the heat exchanger outlet with respect to their constituents and amounts.

In a supermarket, air at atmospheric pressure and 25 °C is supplied to an air handling unit through a rectangular duct with a cross section of 0.5 m x 0.1 m. The air handling unit will distribute 2/3 of the air to the large shopping area of the supermarket at 25 °C, and it will cool the remaining air to -5 °C and distribute it to a walk-in refrigerator. To avoid frictional pressure losses, the average air velocity in the...
