The calculated thrust load at the last cross section in the exit piping. If there is no manifold, then this is the external thrust load acting on the piping system. If there is a manifold, then this thrust is opposed by tension in the pipe wall at the junction of the exit piping and manifold. For more information, see the graphics in Orifice Flow Conditions/Exit Pipe End Flow Conditions/Manifold Pipe End Flow Conditions.
