A pressure–volume diagram (or PV diagram, or volume–pressure loop) is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics, cardiovascular physiology, and respiratory physiology. PV diagrams, originally called indicator diagrams, were developed in the 18th c… Webb1 juni 2024 · There are two loops in the PV plot. The upper, larger, one represents the power stroke and the lower one is the exhaust stroke. The mechanical work generated for each cycle of the engine is proportional to the areas inside the PV diagram loops. The power stroke being positive work and the exhaust stroke is negative work.

WebbA PV diagram is most widely used in thermodynamics to describe corresponding changes in pressure and volume in a system. Each point on the diagram represents different state of a gas. PV diagram of Isothermal Process and Adiabatic Process is similar but Isothermal graph is more tilted. WebbpV diagram of Otto Cycle. The area bounded by the complete cycle path represents the total work done during one cycle. The Otto cycle is often plotted on a pressure-volume diagram ( pV diagram) and a temperature-entropy diagram (Ts diagram).

The theory behind that is the infinitesimal production of work dW = +- p dV, the sign (+-) depending on your convention for the dU being dQ + dW or dQ - dW - anyway, you can get the sign by thinking whether it was an expansion or a compression. So the work in a transformation is W = +- ∫ p dV from A to B ...
