QUESTION:
One lbm of butane (C4H10) is burned with 25 lbm of air that is at 908F and 14.7 psia. Assuming that the combustion is complete and the pressure of the products is 14.7 psia, determine (a) the percentage of theoretical air used and (b) the dew-point temperature of the products.
ANSWER:Step 1 of 7
Butane is burned with air. The masses of butane and air are given. The percentage of theoretical air used and the dew-point temperature of the products are to be determined.
Assumptions are
1. Combustion is complete.
2. The combustion products contain , , and only.
3. Combustion gases are ideal gases.
The molar masses of C,, and air are , , and , respectively (Table A-1).
