Liquid ethyl alcohol (C2H5OH()) at 25oC is burned in a steady-flow combustion chamber with 40 percent excess air that also enters at 25oC. 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 25oC 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.
