a) Methanol CH3OH is a hydrocarbon fuel which is liquid at room temperature. Determine the equation for stoichiometric combustion (chemically correct combination) for Methanol and air. (6 marks) b) A small gas furnace uses Methanol CH3OH fuel (see FIG. Q3b). The air and fuel enter the furnace steadily at a temperature of 298K at volumetric/molar airfuel ratio of 30:1. The reaction occurs at 1 bar and goes to completion. The final gas temperature is measured as 1000K. i) Determine the chemical equation for combustion of Methanol at volumetric airfuel ratio of 30:1 (excess air). (6 marks) ii) Calculate the volume of air required per kg and per kmol of fuel. (6 marks) iii) The final gas temperature is lower than the adiabatic flame temperature due to heat loss from the combustion chamber. Using the resource 'Thermodynamic and Transport Properties of Fluids', and the table 'enthalpy of formation' provided in the equation sheet, produce a table of enthalpy of formation, and sensible enthalpy for the reactants and products. (4 marks) iv) Using the First Law of Thermodynamics: Q=nP(hfo+hho)PnR(hfo+hho)R
