An approximate method for rapid determination of the pressure change for subsonic flow of a compressible fluid under the simultaneous action of heat transfer, friction, rotation, and area change is developed. In the development of this method, the momentum equation was approximated and rearranged for a convenient solution employing charts. This report presents both the analysis involved in simplifying the momentum equation and the charts necessary for obtaining particular solutions. The charts provide a step-by-step solution which converges to an exact solution as the number of steps is increased.
