IAPWS92_RHOL_SAT

This function returns the saturated liquid density of water as a function of temperature using the IAPWS-92 supplementary release fit.

The correlation is:

\rho_l^{sat} = f(T)

where T is saturation temperature and \rho_l^{sat} is saturated liquid density.

Excel Usage

=IAPWS92_RHOL_SAT(T)

• T (float, required): Water saturation temperature (K).

Returns (float): Saturated liquid water density at the specified temperature (kg/m^3).

Example 1: Saturated liquid density near room temperature

Inputs:

T
300

Excel formula:

=IAPWS92_RHOL_SAT(300)

Expected output:

996.509

Example 2: Saturated liquid density near boiling point

Inputs:

T
373.15

Excel formula:

=IAPWS92_RHOL_SAT(373.15)

Expected output:

958.347

Example 3: Saturated liquid density at elevated temperature

Inputs:

T
450

Excel formula:

=IAPWS92_RHOL_SAT(450)

Expected output:

890.344

Example 4: Saturated liquid density near critical temperature

Inputs:

T
640

Excel formula:

=IAPWS92_RHOL_SAT(640)

Expected output:

481.945
