Which of these pose a problem in constant pressure boundaries?

(a) Velocity

(b) Flow direction

(c) Density

(d) Heat flux direction

This question was posed to me by my college professor while I was bunking the class.

My query is from Boundary Conditions topic in division Boundary Conditions of Computational Fluid Dynamics

Correct choice is (b) Flow direction

To explain: Constant pressure boundaries are used when the velocity is unknown. The main problem in this is the flow direction. It has to be found while solving the flow properties.
