Are you talking about the Bernoulli diagram? It's correct, but not applicable. In a closed system with incompressible fluid, the pressure will be lower and the flow velocity higher where the path is constricted.
If you're talking about the static pressure diagram that I posted, static pressure will be constant along the entire run because the flow path has uniform cross section.
