A constriction in a pipe will cause the velocity to rise and the pressure to fall at section 2 in the throat. The pressure difference is a measure of the flow rate through the pipe. The smoothly necked-down system shown in figure below is called venturi tube. Find an expression for the mass flux in the tube as a function of the pressure change.
