Question

can someone help me how to derive the Bernouli's equation in fluid mechanics

Answer 1

I don't know how to do it but check this link:

We shall derive Bernoulli's equation by starting with the conservation of energy equation. The most general form for the conservation of energy is given on the Navier-Stokes equation page. This formula includes the effects of unsteady flows and viscous interactions. Assuming a steady, inviscid flow we have a simplified conservation of energy equation in terms of the enthalpy of the fluid:

ht2 - ht1 = q - wsh
