For a boom sprayer with 8 nozzles, what is the GPA rate if the output per nozzle is 0.87 gpm and traveling at 1.5 mph?

To determine the GPA (gallons per acre) rate for the boom sprayer with 8 nozzles, we first need to calculate the total flow rate produced by all the nozzles. Each nozzle produces an output of 0.87 gallons per minute (gpm), so for 8 nozzles, the total output is:

Total Flow Rate = Number of Nozzles × Output per Nozzle

Total Flow Rate = 8 nozzles × 0.87 gpm = 6.96 gpm

Next, we need to convert the speed of travel from miles per hour to feet per minute, which will help us relate this to the GPA calculation. There are 5280 feet in a mile and 60 minutes in an hour:

Speed in feet per minute = 1.5 mph × 5280 ft/mile ÷ 60 min/hour = 132 feet per minute

Now, we calculate the area covered in one minute. Assuming a boom sprayer width of 1 boom equals a specific coverage width (let's assume a common width of 20 feet for calculation purposes, though the actual width would be based on the specific sprayer being used), the area covered in one minute
