Around airports jet aircrafts can become major contributors to pollution, and as aircraft activity increases and public concern brings other sources under control, the relative contribution of aircraft to pollution could go up. Recently, federal-, state-, and local government pressure has speeded the introduction of new combustors in aircraft. In a test for an aircraft fuel with the average composition C_1.20H_4.40, the fuel is completely burned with the exact stochiometric amount of air required. The air is supplied at 24°C and 100 kPa, with a humidity of 85 percent. For entering air, compute the percentage relative humidity
