Mark where the level string ties to the stake. Let’s say for this example you moved the string up 0.5″ (meaning the current drop is 0.5″). Assume the length between the stakes is 6 feet and you want a 2% grade. 1/4″ x 6 = 1.5 inches.

What is a 1 in 60 fall?

A gradient of 1:60 means that there will be 1 unit of fall for every 60 units of patio width. The patio is to be 4.2m wide, so if that distance (the run) is divided by 60, the result is the 1 unit of fall. … A 1:0.5 slope means that for every 1 metre along the ground, the slope height increases by 0.5 metres.

Typically, you can use the industry standard ratio for fall of 1:80. However, this could differ depending on your project. In this example, that means that the patio should fall 1 unit for every 80 units of distance. So in this example, to find the fall you need to divide the distance run by 80.

How do you calculate gradients?

To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates). If the answer is a positive value then the line is uphill in direction.

What is a 1% slope in inches?

Randy, 1% as a decimal is 0.01 and hence the slope is 0.01. That means for a run of pipe of a certain length the rise must be 0.01 times the length. Thus for you example, since the length of the run is 80 feet which is 80 × 12 = 960 inches the rise must be 0.01 × 960 = 9.6 inches.
