Guess Momentum add value -- CFD Online Discussion Forums

Jackie Guest Posts: n/a	Hello all, Could anybody Explain how to guess the momentum source input value in tube please. I'm simulaing the flow in an open end tube which has the momentum source inside. I expect 0.1 m/s velocity at the position adding the momentum . I know the cross section area of the tube and the volume of the 3D region of the source and the unit of the momentum source is kg/m^-2s^-2. Does any body have an idea how to guess it ( equation and method ) I'm looking forward to hear the kindly help soon, @T_T@ Thank you in advance. Jackie
