Amount of heat required to change the temperature of one unit of volume by one unit of temperature:
c_v = \frac{\delta Q}{\delta V \cdot \delta T} |
Symbol | Dimension | SI units | Oil metric units | Oil field units |
---|---|---|---|---|
M L-1 T−2 Θ−1 | J/(m3⋅K) | J/(m3⋅K) |
Volumetric Heat Capacity depends on the way the heat is transferred and as such is not a table property of the matter.
The two major heat transfer processes are isobaric and isohoric which define:
Isobaric volumetric heat capacity | Isochoric specific heat capacity |
---|---|
Both and are characterising the properties of matter and properly tabulated for the vast majority of materials.
Volumetric Heat Capacity relates to Specific Heat Capacity and density of the matter as:
c_v = \frac{c_m}{\rho} |
In many technical papers the "m" or "v" index is omitted which leads to confusion between Specific Heat Capacity and Volumetric Heat Capacity .
The other confusion is made between Volumetric Heat Capacity and Isohoric Heat Capacity .
