Is There a Connection Between Pressure, Temperature, and Velocity in Liquids?

[banerjeerupak]

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.
