When you have a pressurized gas being released by a tank there are two potential sources of thrust - the pressure pushing the gas out of the tank, and the expansion of that compressed gas once it leaves the tank.

this is not a thrust that is the result of combustible
gasses , it is simply air that is compressed.

I would like to see your results from the following


and your explaination of it.

although it is a absolute meaningless part of the formula
according to you , do you honestly think that there will be no mass comming out of the tube therefore there will be zero velocity.
