Interesting Bob.
From your description, I’m picturing something like the small hose
attachments that make for a pressure sprayer attachment, like those that you
can pick up at your local hardware store?? Not sure I have it pictured correctly tho, and also not sure
what you mean by cross section pipes.
Can you help by explaining your concept again, from a little different
view? I’d like to understand what you mean. Thx, Mike -----Original
Message----- Mike and
All I've been trying to say this for a while. Large cross
section pipes allow the little ones to travel slowely even under high
pressure. Transition into a smooth small diameter hose. 1/'2"
or 3/'8" The 'gun should be selected to have largest possible
innards so the velocity is low. Finally the jet. The jet can be a
straight ahead open hole. cut accross the hole is a vee cut that
allows the pressure to escape to form a flat fan shaped spray. No
sharp turns except that last one. Lower pressure will slow the
impact during this last part of the trip. But the spray
operator is going to want to have choices of spray shape. Dont know
how to handle that. I'm with
you Mike Hitting the leaf seems like the nost gentle part of the
trip. Bob Mike Bosko <mjbosko@jmtsystems.com> wrote: Seems to me that theyre
getting splatted against things immediately before leaving the sprayer thats
how the sprayer works. Pressure
builds up in the tank, and then the water hits a fitting at the end of the hose
connecter that in turn, makes the spray fan out and maintain pressure. I cant imagine how that could be any
better than flying through the air for a while and then hitting a plant even if it were a jet stream, it seems
better than what the sprayer nozzle does to them little critters. Maybe Im thinking about
this too much again, I dont know. -m -----Original Message----- Pressures up to 70 PSI are what you can expect from a pump
sprayer. This is fine for the microbes. The problem is the velocity at
which they hit things. That is where you need to be most careful. Splatted
microbes are dead ones....Spraying is an art. Cheers, Jeff
