See pressure, velocity, and turbulence shape moving fluids.

Continuity assumes steady, incompressible flow. Viscosity, turbulence, and real pressure losses are deliberately left for a deeper model.

Widen the pipe and the same flow slows down. Continuity conserves flow rate; it does not say pressure is always uniform.
