Notes
- Values calculated by Emsal using the IAPWS-IF97 formulation. Absolute pressure = gauge pressure + 1.013 bar (sea level).
- hf is the enthalpy of water at saturation temperature and hg that of dry saturated steam; hfg = hg − hf is the latent heat — the part used for heating and not recovered in the condensate.
- vg is the specific volume of dry saturated steam; it is used to calculate pipe size and steam velocity (density = 1 / vg).
- In the vacuum rows, pressure is given as absolute (below atmospheric).
- Accuracy and currency are not guaranteed; use the current edition of the standard for design and purchasing decisions. How the library is compiled →
