- 30 Pts 3 Butane C4h10 Is Burned With Stoichiometric Air And The Products Are Cooled To 20 C A Provide The Correct 1 (77.09 KiB) Viewed 37 times
[30 pts.] 3. Butane C4H10 is burned with stoichiometric air and the products are cooled to 20°C. a. Provide the correct value for D in the butane reaction with air: C4H10 + A(O2 + 3.76N2) = BCO2 + CH20 + DN2 b. Assuming complete combustion at P = 100 kPa, determine the air-fuel ratio. C. For this reaction (butane burned with stoichiometric air), what is the due-point temperature (i.e., the temperature at which the moisture will just begin to condense) of the products assuming Patm = 100 kPa? Hint: Don't interpolate. Just provide the closest value of the temperature and explain how it was obtained. (a) D = 24.4 (b) AF = 15.47 kg air/kg fuel (c) From Thermodynamic Property Tables, Table A-5, for saturated water with pressure entry, we approximate Tsat = 53.96°C @ Psat = = 15.0 kPa
