What is the speed of travel if the sprayer application rate is calculated based on collecting 287 ml of water in 15 seconds and nozzle spacing is 20 inches?

To determine the speed of travel based on the given sprayer application rate, start by calculating the application rate in gallons per acre (GPA).

First, convert the collected volume of water from milliliters to gallons. There are approximately 3,785 milliliters in a gallon. Therefore, if you collected 287 ml, this can be converted as follows:

287 ml ÷ 3785 ml/gallon ≈ 0.0759 gallons.

Next, the time duration is 15 seconds. To find the application rate in gallons per minute, multiply the volume by a conversion factor:

0.0759 gallons × (60 seconds / 15 seconds) = 0.3036 gallons per minute.

Now, move to the calculation of the speed, knowing that the application rate is based on the nozzle spacing. The nozzle spacing is given as 20 inches. To calculate the area covered in one minute, find out how many passes are made in that time.

First, convert the spacing from inches to feet:

20 inches ÷ 12 inches/foot = 1.6667 feet.

Now, calculate how far the sprayer travels in one minute. Speed is determined by how much area can be treated in a
