WebAssume non viscous flow and constant cross sectional area. In this case, Bernouli's equation states velocity would increase at the discharge section, as its gage pressure is zero, thus lower than inside the pipe. What I do not understand is that conservation of mass equation states velocity is constant as cross sectional area is the same.
