D.3.3. Liquid Specific Heat (Heat Capacity, Liquid)

Liquid Heat Capacity or Liquid Specific Heat is tagged LiquidSpecificHeat. This property is tabulated against temperature and used in the vaporization model of liquid fuels. It is a 5-coefficient correlation with units of J/kmol-K.

The first number in the tag is an integer indicating the type of the correlation and the next five numbers are the five correlation coefficients: A through E. The liquid specific heat calculation uses two types of correlations (mutually exclusive). The type of correlation is determined based on the first ID tag that is either 1 or 2. The Type 1 correlation ( Equation 3) is most commonly used. However, a few components, such as n-butane and n-heptane, use the Type 2 correlation ( Equation 4).
