    section‚ their is a negative pressure gradient i.e‚ in layman terms fluid is trying to flow from low pressure region to high pressure region according to Bernoulli equation. In this adverse pressure gradient‚ there is boundary layer separation‚ in simple terms‚ the fluid leaves the surface of the wall. Due to this there can be energy loss or the fluid can’t recover the pressure fully leading to head loss. So if divergent section is long that means more gradual diverging section‚ due to which the adverse
