WebbThe contrast between the normal PV-Diagram and the fault PV-Diagram that was brought with a decrease in spring stiffness is shown in Fig. 2. The PV-Diagram after normalization with the first method is shown in Fig. 3. The maximum pressure was transformed into 1, and the relative shape of the normal and the fault PV-Diagram was changed. Webb10 okt. 2024 · 3. Not sure what areas you mean, but the work ( W = ∫ p d V) on the system for path A is the area under the projection of A onto the V-axis, and the work done on the system for path B is the area under the projection of B onto the V-axis. The area under A is greater than B, thus more work is done on the system for process A than B.
