Pressure Temperature Relation

  1. May 18, 2010 #1
    Is there a relation between pressure/velocity and temperature for liquids. Something like the ideal gas law for fluids in general?

    Do you mean pressure/volume or pressure/(sound)velocity?

    In general fluids are more complex. In an ideal gas you assume that the molecules never touch and so it's just newtonian mechanics of perfect points moving around. With a liquid all the properties depend on interactions between the molecules of the fluid

    I can not assume it to be compressible fluid. So the ideal gas law is ruled out.

    I mean the pressure (volume) and temperature.
