How can I derive my own stream from a standard stream?

WebDec 14, 2024 · To derive Bernoulli’s equation, we first calculate the work that was done on the fluid: d W = F 1 d x 1 − F 2 d x 2 = p 1 A 1 d x 1 − p 2 A 2 d x 2 = p 1 d V − p 2 d V = ( p 1 − p 2) d V. The work done was due to the conservative force of gravity and the change in the kinetic energy of the fluid.
