Question

Pressure velocity relation for compressible fluid

Answer 1

In a nozzle, the exit velocity increases as per continuity equation Av=constAv=const as given by Bernoulli equation (incompressible fluid). Pressure is inversely proportional to velocity, so we have lower pressure at the exit of the nozzle.

Answer 2

Pressure is inversely proportional to velocity as per compressible fluid flow.Hope this may help u
