WebIn the figure shown below. Heat is added, a compressor is doing work on the system, the flow entering the system does work on the system (work = -p 1 V 1), and work is done by … WebFrom the non-flow energy equation Q = u 2-u 1 + W For an adiabatic process Q = 0, we have -W = (u 2-u 1) or W= (u 1-u 2) This equation is true for an adiabatic non-flow process whether or not the process is reversible. In an adiabatic compression process all the work done on the fluid goes to increasing the internal energy of the fluid.
