Problem 4) LHV and HHV of Fuels Consider the following list of some fuels with their LHV and HHV. a) Provide a plot of the LHV as a function of the molecular mass of the fuel. Group the fuels in categories and discuss any correlation between the heating values and the molecular mass. b) Provide a plot of the percentage increase of the HHV relative to the LHV as a function of the molecular mass of the fuel. Discuss any correlation or generalization. Fuel LHV and HHV LHV Methane (CH4) Propane (C3H8) Isooctane (C8H18) Cetane (C16H34) Methanol (CH40) Ethanol (C2H60) Carbon Monoxide (CO) (MJ/kg) 50.0 46.4 44.2 44.0 20.0 26.9 10.1 HHV (MJ/kg) 55.5 50.4 47.8 47.3 22.7 29.7 10.1
