Question

A gaseous-s mixture of 2 (by volume) acetone and 4% ethanol in air is at 25^degree C and a pressure of 1 aim. Data Acetone (C_3H_60) has Delta h_c = - 1786 kj/g mol Ethanol has Delta h_c = 1232 kJ/g mol Atomic weights: H = 1 mole. C = 12 moles. 0=16 moles aim N = 14 moles Specific heats. c, i = 1 kJ/kg K. constant for each species For a constant pressure reaction, calculate the partial pressure of the oxygen in the product mixture. Determine the adiabatic flame temperature of this mixture. If this mixture was initially at 400^degree C. what will the resultant adiabatic flame temperature be?

Explanation / Answer

Answer (a). 32 bar

Answer (b). 2500 Deg C

Answer (c). it will be the same as flame temperature ie 2500 Deg C
