Pipe line slope can be calculated using the formula: slope = (rise/run) x 100

• Measure the distance between two points on the pipe line

• Measure the difference in height between the two points

• Divide the difference in height by the distance between the two points

• Multiply the result by 100 to get the slope percentage

• Example: If the distance between two points is 10 feet and the height difference is 2 feet, the slope would be...read more
