I am going to use a rolling Shop-Vac (trade name) and 2.5" hose. I want
to use it to pick up pecans to be easier on my back, and to put them
into a 55 gallon barrel, making them more effective to handle. I know
that some shop vac systems have piping that goes a long distance. I
would ideally like to go two sections of hose, and that would be 40 to
50 feet depending on the hose. How much drop of suction and efficiency
would I experience through that length, with only one opening at the end
of the hose?

thanks

Steve
