I am glad that some people are interested. I tried to solve it by a CFD software; but I am not satisfied with the results. I've got either a wrong result, or a result that I don't have any idea how it comes, where it comes. Actually, I am just learning CFD, so don't trust my results on it. If...

I didn't consider the space effects actually. I assumed that it is a simple work-energy problem; so ignored many things. I assumed that once it reaches to the orbit, the net force will be zero, so the satellite will neither go further, nor fall back.

Sorry, you may be right; I will erase the calculation part.

I don't know the exact English terms, but I will try to explain what I know: E: Energy [J] P: Static pressure [Pa] u: Velocity of the object [m/s] G: Gravitational acceleration [m/s 2 ] z: Elevation [m] m: Mass of the object [kg] V: Volume of the object [m3] 1: point 1 2: point 2 The...

Hi, even though it seems so simple; I can't solve this since a few days and it's driving me crazy. Flow gets inside the tube from point 1, it will create a vacuum, which will let a secondary flow inlet from point 2. Both flows will mix inside the tube, and get out of the junction from point...

Hello everyone, It's nice to see that the people are taking this forum serious. I am an energy engineer, looking forward to help each other. Thanks a lot, Cajamarcus
