Homework Help: Adiabatic process for water

    I was just wondering if there is a relationship between Pressure, Temperature , and Volume like there is for Ideal Gases, but for water.

    ie. for Ideal Gas:
    TV^(gamma-1) = constant
    PV^gamma = constant

    Any insight would be greatly appreciated,

    Thanks in advance.

    Water in its liquid or solid state is virtually incompressible, so there is little volume change even under very high pressure. So there is not much work that is done when increasing pressure to water. If there is not much work done and no heat added (because it is adiabatic), there is no not much change in internal energy (ie. temperature) with pressure.

    Bernoulli's equation explains how the speed of water will change with dynamic pressure when water is flowing.
