New answers tagged internal-energy
You do not need any of those formulae. If the fluid is incompressible, no work can be done on it. If the flow is also adiabatic, no heat is transferred from one particle to other. Now visualize a fluid element in its rest frame. Since no work and no heat is transferred to the element, the change in its internal energy is zero. If internal energy is supposed ...
