Saturated Steam Table by Pressure

Saturated liquid and vapor properties indexed by absolute pressure, generated from the same IAPWS-IF97 engine as the calculator.

Each row gives the saturation temperature, specific-volume endpoints, enthalpy, and entropy at one absolute pressure. Subscripts f and g identify saturated liquid and saturated vapor. The fg columns are vaporization differences between those endpoints.

Select a pressure in the first column to open an x = 0.5 state in the calculator. Change x to zero or one for a single endpoint. A 10 bar row means 10 bar(a); enter gauge setpoints with barg or psig in the calculator.

Use the calculator for an unlisted pressure or more display precision, especially near the critical point. For a temperature lookup, use the temperature-indexed table. The methodology page lists the engine version and verification results.

Saturated water and steam. Pressure is absolute. Coordinates are shown without padded zeros; calculated properties use six significant figures.
