Hello Sir,

i have little trouble to assign the boundary condition for pressure.
please tel me in pipe flow problem of laminar model.

I simulate the result for horizontal pipe in which air and water passes from the inlet and at the outlet atmosphere condition.
so how can i set Boundary condition for pressure?

and please tell me what is meaning of that ref.pressure and how we calculate total pressure at outlet atmosphere condition?

please tel me.

hoping for positive reply.

Dear Jignesh
pressure is linear term so it can be calculated as gauge value
if your outlet has atmosphere pressure determine your ref.pressure to zero
