1. The problem statement, all variables and given/known data 2. Relevant equations P1+pV12/2+pgh1=P2+pV22/2+pgh2 3. The attempt at a solution My thinking: since the pitot tubes measure the stagnation pressure (static + dynamics pressure) and the height of the tubes are the same. By Bernoulli's equation, the total pressure along a streamline is unchanged, therefore there is no pressure change between two tubes which gives h=0. I just want to check is my thinking correct or not. Thank you!
