How do you calculate the net work then? That is what I struggle with. I do not understand that part.

You have to know the gas density curves. Combustion gases have their own densities which are different from air, and their densities change with temperature. Air for instance decreases in density with heat, CO2 also decreases in density but at a much lower rate, and the starting molecule is denser than air, supercritical CO2 would be perfect for gas turbines for this very reason. Likewise for NOx and other particulates. The heat, mass, and density contribute to the mean effective pressure generated. Turbochargers lose efficiency when they heat the air too much because air density drops with heat, this is why intercoolers make more power despite a pressure loss. The density of the gas is higher, thus has higher moment of inertia, it also has a lower kinematic viscosity.
