The equation of state gives a relationship between the pressure,
density and temperature. It can take several different forms depending
of the situation being modelled. For example, when considering a
uniform incompressible fluid it is simply
 |
(2.10) |
For a perfect gas, it is
 |
(2.11) |
where
is the gas
constant, so that the pressure proportional to both the density and
temperature. The temperature must then be given by an energy
equation (or specified as a constant).
