What is the grade of a rise of 6 ft in 600 ft?

• A. 0.1 %
• B. 1 %
• C. 2 %
• D. 10 %

Answer: (B)

To determine the grade of a rise of 6 feet over a horizontal distance of 600 feet, the formula for calculating grade as a percentage is used. The grade percentage is calculated by taking the vertical rise, dividing it by the horizontal run, and then multiplying by 100 to convert it into a percentage. In this case, the vertical rise is 6 feet, and the horizontal distance is 600 feet. The formula can be broken down into two steps: 1. Divide the rise by the run: \[ \text{Grade} = \frac{\text{Rise}}{\text{Run}} = \frac{6 \text{ ft}}{600 \text{ ft}} = 0.01 \] 2. Convert to a percentage: \[ 0.01 \times 100 = 1\% \] Thus, the calculated grade of the incline is 1%. This means the correct answer accurately reflects the relationship between the rise and the run given in the question. Understanding this calculation is crucial in wastewater collection, as it helps in assessing the slope needed for efficient wastewater flow in pipes.
