The ideal Otto cycle, shown in the figure above, is the cycle used by gasoline engines to generate useful work. It consists of an adiabatic compression from step 1 to 2, followed by an isochoric increase in pressure from step 2 to 3, followed by an adiabatic expansion from 3 to 4, and finally an isochoric decrease in pressure from step 4 to 1.Consider an Otto cycle that works on a monoatomic ideal gas (γ= 5/3,cV= 3R/2), initially at a...

A polytropic process for an ideal gas in one in which pressure and volume are related by = const., where n is a constant. It is a generalization of the special processes considered earlier. Thus n = 0 defines an isobaric process, n = cp/cv an adiabatic process, n = 1 an isothermal process, and n = 8 an isochoric process. Suppose 1 kg of dry air at 280 K and 100 kPa undergoes a polytropic expansion in which the...
