# .BuildSysPro.IBPSA.Media.Refrigerants.R410A.specificIsochoricHeatCapacityVap_Tv

Function that calculates the specific isochoric heat capacity of R410A vapor based on temperature and specific volume

## Information

Function that calculates the specific isochoric heat capacity (cv) of R410A vapor based on temperature and specific volume.

The specific isochoric heat capacity is evaluated from the partial derivatives of the Martin-Hou equation of state.
