If a sprayer's effective swath width is 40 ft and is calibrated for 40 lbs per acre, what is the expected pounds delivered per minute at an application rate of 0.2 acres per minute?

To determine the expected pounds delivered per minute, we start by recognizing that the application rate is 40 lbs per acre. If the sprayer is calibrated to deliver this rate and operates at 0.2 acres per minute, we can calculate the total amount delivered in a minute.

By multiplying the application rate (40 lbs per acre) by the area covered per minute (0.2 acres), we get:

40 lbs/acre × 0.2 acres/minute = 8 lbs/minute.

This shows that at an application rate of 0.2 acres per minute with the sprayer calibrated for 40 lbs per acre, the expected pounds delivered per minute is indeed 8 lbs.

Therefore, the correct response highlights how the application rate and the operational speed of the sprayer relate directly to the amount of pesticide delivered in that specific timeframe. This calculation is a fundamental aspect of ensuring precise pesticide application in aquatic weed control, which can affect both effectiveness and compliance with regulations.
