Naturally your tank will run out quicker--and you will spend a lot of time driving back to the truck, refilling the tank and mixing new chemicals.
Suit your speed to the situation. Herbicides and insecticides 4 mph. Some odd product that requires four times as much water per thousand--just go 1 mph.
Apparently I am not able to make my point. First I personally don't believe in applying anything less than a Gallon per Thousand. Fact is I have a 150 gallon rebuild Toro Ride on sprayer from a Golf Course that sprays 5 gallon per thousand at 4 MPH. Only after plumbing it with big hoses as well as proper pump size was I able to get that calibration. Therefore 2 gallon per thousand isn't wrong in my book.
BUT MY POINT WAS NOT ABOUT A BIGGER PUMP, BUT WHAT SIZE PUMP
IS NEEDED TO DELIVER 2 GALLONS PER THOUSAND. I was trying explain WHY/HOW math is used to engineer and Design a boom sprayer. I am not able to get my point across because # 1 I might not be a Good Teacher or # 2 I don't have students able to understand the Ideas I present to them.
