Pressure plot analysis
 
https://lh5.googleusercontent.com/-f...ure%252529.PNG

This is my pressure plot in my attempt to analysis the fluid flow in Venturi Tube. I am wondering if my result is correct or not. The fluid flow within the Venturi Tube is set to be laminar and negative pressure occur at the throat section. The hole represent the tapping for manometer.

Any opinion and advice are welcome, Appreciated it^^

Why pressure is not lowest at the throat?

The pressure is still lowest at the throat section. I setting the inlet section as velocity inlet and outlet section as pressure outlet, no boundary condition are set for the tapping hole. Is this correct way?? Because I want to found out the static hole error cause by the tapping hole on Venturi Tube.
