I have a problem here. I don't get why the stagnation pressure equal the height of the water in the pitot tube.
The liquid manometer is easy. We analyse the forces on the horizontal contact surface of the tube and the liquid manometer so P1 = Density * g * h
However I fail to analyse the forces on the curved section of the pitot tube. How can I prove that P2 = density* g H
so I can use P2 - P1 = density *g (H-h)
