What is this conservation of energy

Im very bad in basics to understand
here all fluids > Bernoulli's equation we got P+1/2 v^2/2+rho*g*h Here instead of p can we insert Internal energy U as we do in First law of thermodynamics. If yes, then can we say that Internal energy can also be any energy acting inside a system (Microscopic and macroscopic). If no why is that?

Bernouilli is valid only for fluid of constant density and in absence of any dissipative action...
