Hi, I could really use help. I am trying to understand what would happen to the velocity of a freestream air if it loses mass while traveling down a tube. For example, suppose that you have 1 cubic meter of air traveling at 10 m/s down a duct with a 1m^2 cross section. And then suppose that you lose via pumps along the tube 90% of the air. Or another way to say it... suppose that 90% of the air just disappeared as it was traveling down the pipe. What would be the resulting velocity of the remaining air? My closest guess is that it would be reduced to 1 m/s. Is that right? Thanks!
