1 kerosene decane c10h22 with a density of 493, Ask an Expert

Academics

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.
