Real-fluid P–h chart (NIST-quality embedded property data): hover for state values, click to place points A–D, toggle property lines.
State points
Click the chart to place A, B, C, D in turn; drag to move. Or type P + T (single phase) or P + x (two-phase) and press Enter. The process path chains the placed points in order.
Cycle builder
Computes the cycle and places its states as points A–D (A = compressor/turbine inlet). Manually moving or editing a point switches the cycle off.
