Question:

Devise a general scheme for analyzing four-step air-standard power cycles. Model each step of the cycle as a polytropic process described by
PVδ = constant
which implies that
TP(1 − δ) ⁄δ = constant
with a specified value of δ. Decide which states to fix, partially or completely, by values of T and/or P. Analysis here means determination of T and P for initial and final states of each step, Q and W for each step, and the thermal efficiency of the cycle. The analysis should also include a sketch of the cycle on a PT diagram.
