Given the enthalpy of formation for food waste to be -394.7 MJ/kmol, use the combustion reaction from Equation 4.11 to calculate its HHV (assume that the molecular formula is the same as switchgrass). Repeat this calculation for redwood (assume an enthalpy of formation of -50.7 MJ/kmol).
Equation 4.11
1. Four (4.0) lbm of CO2 are contained in a piston-cylinder system. The CO2 is initially at a temperature T1=500°R and pressure p1=20 psia. The CO2 undergoes the following two processes:
