When calibrating a sprayer, if you collect 331 ml of water in 15 seconds, what is the application rate in gallons per acre (GPA) with a speed of travel at 6 miles per hour?

To determine the application rate in gallons per acre (GPA), it's essential to convert the volume of water collected and consider the speed of travel.

First, you collected 331 milliliters of water in 15 seconds. To convert milliliters to gallons, recognize that 1 gallon is approximately 3785 milliliters. Therefore, you can convert 331 ml to gallons as follows:

331 ml × (1 gallon / 3785 ml) = 0.0874 gallons.

Next, calculate the sprayer's output per minute, since the application rate is typically expressed in gallons per acre per minute. This can be done by multiplying the amount you collected in 15 seconds by 4 (since there are 60 seconds in a minute):

0.0874 gallons × 4 = 0.3496 gallons per minute.

Now, to determine the area covered in one minute while traveling at 6 miles per hour, convert the speed into feet per minute:

6 miles/hour × 5280 feet/mile ÷ 60 minutes/hour = 528 feet/minute.

Now, to calculate the area covered per minute in acres, recall that one acre is 43,560 square feet. Therefore:

Area covered
