Engine Cycle
In order to power the generator required to generate electricity for the industrial water usage, design a closed-system air-standard gas power cycle composed of four processes and having a minimum thermal efficiency of 40 percent. The processes may be isothermal, isobaric, isochoric, isentropic, polytropic, or pressure as a linear function of volume. Prepare an engineering report describing your design, showing the system, P-v and T-s diagrams, and sample calculations. Explain in detail the processes mentioned above and the differences between the Otto and Diesel cycle using diagrams to buttress your points.
