Petrol is used as a fuel in one of the engines for the industry you are working for. It typically consists of 35% propane, 30% butane, 12% ethane, 16% ethylene, and 7% propylene. While you were doing your rounds, checking the equipment, an operator told you that he thinks that the orsat apparatus is broken. The exhaust gas analysis provided by the apparatus seem to be fluctuating. In order to check if the values of the apparatus is right, you decided to compute for the theoretical values. a. You assumed that the air used is provided 35% in excess. What is the exhaust gas analysis theoretically? b. Assuming that in a day, the machine uses 50 m3 of petrol (p=780 kg/m³), how many m of exhaust gas (T=400°C, P=740mmHg) is produced? C. From (b), how much air (T=23°C, P=740mmHg, 70%RH) in m is needed?
