Water wagon

[550Doug]

I"d like to mount a water tank on a wagon to water my garden using a PVC type boom on the back (3 water spouts). But I know very little about pumps to use or flow rates. I"m guessing a flow rate of about 10 GPM would water 3 rows at a time while travelling about 1 mph. What kind of a pump would do the job? A PTO driven unit or an electric one?
Thanks

You might not need to rig up a pump. Don't know what size tank you have or the size of the outlet on the tank and if I decipher this right, you are thinking of a horizontal boom going across the rows, but if the boom was, say, 1 1/2" tubing with a 7/8" or 1" hole over each row with a round splash pan a couple of inches under each hole to get the water to spray out in somewhat of a circle you might have a working system just from gravity feed. Feed the boom with a 1 1/4 inch hose, but of course the outlet hole in the tank will have to be big enough to let it out that fast. The boom might have to be fairly close to the ground to avoid splashing dirt up on the plants. Just a thought! You won't have the expense and bother of a pump this way Jim

Doug - I use 2 plastic "food grade" tots on an old army trailer for that. I use soaker hose and let gravity do the rest. That also saves on water. Jim

Rule of thumb is 1" / week, at least around me. Between rain & watering it. I suspect that's a bit high, but it is what is for planning Preferrably in one shot so it can soak deep, rather then 2 or 3 shallow ones that dry quick and encourage roots to develop near the surface.

1s.f. x 1" of water = 144 cubic inches; 231 c.i. to the gallon.

So figure on about 1/2 gallon a week per s.f. of garden. Just scientific wild @ss guess worw, figure 6" wide "zone" around the base of the plants, that's about 1 gallon for every four feet of row you're watering.

5,500' in the mile, divide by 60 = 92 feet per minute. 92 / 4 = 23 gallons per minute to deliver the equivelant to 1" of water over a 6" wide row.
