Liquid ethyl alcohol (C2H5OH( )) at 25°C is burned in a steady-flow combustion chamber with 40 percent excess air that also enters at 25°C. The products leave the combustion chamber at 600 K. Assuming combustion is complete determine the required volume flow rate of the liquid ethyl alcohol, to supply heat at a rate of 2000 kJ/s. At 25°C the density of liquid ethyl alcohol is 790 kg/m3, the specific heat at a constant pressure is 114.08 kJ/kmol-K and the enthalpy of vaporization is 42,340 kJ/kmol.
