Correlation 43 (Kistiakowsky – Watson Equation for Latent Heat)

The following table lists the identification numbers of this correlation with respect to some well-known sources of thermodynamic data.

The equation has the following form:

where

TC is the critical temperature

Tb is the boiling point temperature

You must use 2 coefficients with this correlation.

You can use any temperature unit of measure (UOM) when you input data for this correlation. However, AVEVA Thermodynamic Data Manager converts temperatures to Kelvin (K) before it calculates the property value.

Usage

We recommend that you use this correlation to calculate only the following property:

• Latent Heat of Vaporization
