Let`s say you use a small rc rotor/ electric engine to blow wind through a pipe that has a 90 degree turn in it. Does the wind slow down with 25% because it has to make the turn? Hence does it leaf the pipe after the turn at only 75% of it`s speed? And what about a u-turn pipe. Does the wind loose almost 50% of it`s speed? Or does it loose very little speed or energy? Is there someway to calculate this.
If wind is blown through a corner does it loose 25% of it`s speed?
