Determine the adiabatic flame temperature of propane burned in 100% excess air. Use a heat of formation of propane of -45000 Btu/lb-mole.
For
calculating an "adiabatic flame temperature" it is customary to
assume that the reactants (input) are at the reference temperature
(298 K or 537 oR).
Psi is equal to 3
Your assigned value of wis (You will lose 1 pt if this is blank). Methane (CH) is burned with (110 +0.3 )% of theoretical air. (Hence, if y = 3 the methane is burned with 110.9% theoretical air). The mixture enters the combustion chamber at 25°C. A) Find the Air/Fuel...
Methane (CH4) is burned with 110.9 % of theoretical air. The mixture enters the combustion chamber at 25°C. 1) Find the Air/Fuel ratio for this mixture: AF = (+ 0.03) 2) Find the adiabatic flame temperature for the mixture. Tadiabitic flame = OC (+ 20°C) 3) Find the mole fraction of the N2 in the exhaust. YN2 =

Gas Ethanol (C2H5OH) is burned with 100% theoretical air. The fuel enters at 100 KPa, 25 °C and the air enters at 100 KPa, 27 °C. The temperature of the products is 800 k. Determine the heat transfer.
In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius. The walls have fiberglass insulation, which dominates the heat conduction properties of the wall So we can consider the wall to have a thermal conductivity of k(wall) = 0.048 W/m/K . We will take the thickness of the walls and ceiling to be L(wall) = 12...
Ethyl chloride (C2H5Cl) boils at 12 degrees celcius. When liquid C2H5Cl under pressure is sprayed on a room-temperature (25 degrees celcius) surface in air, the surface is cooled considerably. a) What does this observation tell us about the specific heat of C2H5Cl(g) as compared with C2H5Cl(l)? b) Assume that the heat lost by the surface is gained by ethyl chloride. What enthalpies must you consider if you were to calculate the final temperature of the surface?
