need a math wizzard - cause i'm an idiot...LOL

ok ok so here it goes.. watering an area of 5,671.6 sq ft, with a sprinkler that flows at 5.13 Gpm. how long does it take to put down 1 inch of water - roughly ?

lol

Line for idiots forms here, cuz I haven't a clue, and I'm feeling to lazy to try and figure it out

about 90 minutes

oops. my bad. I forgot that there are 7.5 gallons to a cubic foot of water. it'll take about 5 hours.

I'm next in that line!!

231 Cubic Inches in a gallon of water, Save all the calculations it will take 11.5 hours.

231 cu in in a gallon covers 1.6041667 sq feet one inch deep.....5671.6 divided by 1.6041667 =3535.5428 gallons to do the job
at a flow rate of 5.13 gallons per minute you get 307.8 gallons per hour.....so 3535.5428 divided by 307.8 = 11.486494 hours

holy crap !!!

thanks bro

Are you wanting to put down just an inch or are you waning to put down an inch of infiltrated water. If you are wanting to put down an inch without infiltration it will take about 11.5-12 hours. If you are wanting to put down enough water to infiltrate into the soil an inch that is more variable. If your soils are very clayey you are going to have to put water on it slowly due to the infiltration rate being only .05-.2 inches per hour where as sandy soils can reach infiltration rates as high as 13 inches and hour. It also depends on how large an area your sprinkler is covering at one time. Also rotary sprinklers put down 80% of the discharge over only 60% of its radius, so to get an inch of water over the last 40% of the radius you will end up over watering the rest of it. What type of sprinkler are you using and what are the dimensions of the area you are trying to irrigate?

Hmmm.. infultration watering - soil type is what we call "sugar sand" very powdery / dusty. area= full circle 5,671.625 sq/ft. sprinkler= impact type.

i was guestimating 15 - 20 mins.

I usually figure 2 hours is enough for a good soaking.
