Rankine Cycle 2D: Flow Schematic & Temperature–Entropy Diagram

Watch the four-step steady-flow cycle that turns heat into electricity inside coal, gas and nuclear steam plants, rendered two ways at once: a 2D flow-loop schematic where steam particles visibly travel through the boiler, turbine, condenser and pump, and — underneath it — the same cycle traced live on a temperature–entropy (T–s) diagram against the water/steam saturation dome, the actual textbook tool engineers use to read a heat engine's performance. Boiler and condenser pressures, turbine isentropic efficiency and flow speed are all adjustable, with saturation properties looked up from real steam-table data driving live thermal efficiency, net specific work, heat input and turbine-exit steam quality. Drag or scroll on the T–s panel to pan and zoom into any part of the cycle.
