How to set mass flow rate and pressure in one inlet?
 

Currently, I'm running simulation of heat exchanger which has two different inlet and outlet. One for hot fluid and another is cold fluid. Each inlet has its own mass flow rate and pressure. I use mass flow inlet BC to input the mass flow rate, but I don't know where to input the pressure since the Fluent help said that the value of supersonic/initial gauge pressure is neglected if the condition is in subsonic. My question is what BC I have to use for this condition, especially for the inlet and the outlet.
Thank you
