    Sorry sir but there are certain assumption in bernaullis theorem that
    1 flow is steady
    2 flow is ideal
    3 flow is incompressible or const density so a gas is a complessible and density can vary as per the equation
    v2/g + P/w +y=const

    1.To calculate free energy.
    2.chemical potential is 1 type of force to turn a reaction in equilibrium.
    3.chemical potential is comparable to escaping tendency or fugacity,its means the tendency of reaction flow to ewuilibrium point.
    4.If chemical potential is high escaping tendency will high.
