  I tried to simulate the pressure loss inside a pipe. At inlet i have given 0.2bar at 150kelvin and outlet of pipe is outflow condition. Its showing reverse flow and internal flow rotation. Air is flowing inside. I have uploaded image of inlet. Inlet is at left side

  Don't use outflow. Assuming the density is constant use a velocity inlet & pressure outlet then measure the pressure loss.

  but all i know is the pressure at inlet of pipe
