1. Kerosene (decane, C10H22) with a density of 49.3 lbm/ft3 has a HHV of 20,484 Btu/lbm and costs $0.500 per gallon. Calculate the cost of 1.00 therm (105 Btu) obtained by burning kerosene.
2. The explosive energy of a high explosive is defined to be the lower heating value (LHV) of the detonation reaction. The heat of formation of nitroglycerin, C3H5(NO3)3, is -354 MJ/kgmole, and its molecular mass is 227 kg/kgmole.
a. Find the values of a, b, c, and d in the following reaction describing the detonation of nitroglycerin:
C3H5(NO3)3 → a(CO2)+b(H2O)+c(O2)+d(N2)
b. Determine the explosive energy of nitroglycerin in MJ/kg.
