Yes it does because it shows that the NASA thrust equation is simply stating mass flow rate is force. This is wrong.
Quoting: Anonymous Coward 77456542 Here's something that maybe, just maybe you'll understand.... Since you like FE university of youtube, Explain the movement of the water hose........ [ link to www.youtube.com (secure)] Any objective person will conclude the flow of water is causing opposite reaction force that makes the hose move. Mass flow rate is force. This is high school physics. It’s pushing off the air just like a rocket in atmosphere Utter complete Bullsh!t. 1 gallon of air(at sea level) is about 0.09 lbs. 1 gallon of water is about 9.0 lbs. The molecular density/mass of water is 100 times that of air. Pushing against air is insignificant and immaterial. If rocket thrust was from pushing off air, the forward air résistance would cancel that out. Get a high school physics book and READ IT! Resistance from air is called drag. The faster the exhaust moves through the atmosphere the more drag. Ever heard of the sound barrier and terminal velocity?
