See also: Dupre

The formula of Dupre is an empirical formula making it possible to calculate the saturating Steam pressure according to the temperature. This formula is:

$\backslash \; ln\; (p\_S)\; =\; \backslash \; alpha\; -\; \backslash \; frac\; \{\backslash \; beta\}\; \{T\}\; -\; \backslash \; gamma\; \backslash \; cdot\; \backslash \; ln\; (T)$

• $T~$ Temperature.

• $p\_S~$ Pressure.
• $\backslash \; alpha\; \backslash \; beta\; \backslash \; gamma\; ~$ is of the coefficient which depends on the nature of the fluid.
