“Malo periculosam, libertatem quam quietam servitutem.”
I see from the spelling this must have been an Air Force effort.
Physics will tell you it is the long hose that has the lowest pressure at the end. Might be, the DIAMETER that is most important, eh, what?
one must compute the internal friction coefficient of the hose per foot along with pressure and hose diameter times hose length in order to derive the flow rate in cubic feet per minute. as you are indeed aware, pressure is resistance to flow.
Being a sailor it should read, “navy personnel must aim at the space in between the two you see”
Yep, most assuredly, Air Force. While we love, honor and respect our brothers (and sisters!) from the other branchs, we know these signs HAVE to be posted. LOL
