Many laser levels with digital grade require the grade to be set as a percentage e.g. The other two values and the total distance will be calculated. The gravitational flow form of the Hazen-Williams equation is calculated to provide water velocity and discharge rate that can be achieved through a pipe with provided proportions. Calculated out this gives an angle percentage of 60%. The difference in elevation between points is called the rise. Since this pipeline was calculated with a flow rate of 400 gpm, this example will calculate the head loss for 200 gpm and 800 gpm through the same 100-foot section of 4-inch, steel schedule 40 pipe. "Our mission is to provide the construction industry with a tool to save time and money through simplicity when dealing with complex formulas and calculations in the field.". Slope percentage is calculated in much the same way as the gradient. The longer the pipe, the smaller the slope will need to be. Enter All Pipe Grade Elevation Measurement Values In Decimal Feet ! For example, a slope 20 feet long that drops by 1 1/2 feet has a percentage pitch of 7.5 percent — (1.5 / 20) x 100 = 7.5. Use our angle unit conversion calculators to convert your slope from degrees to another unit of measurement. % Slope = Rise / Run * 100. 1.

What is a 1% slope? 25/12 = 0.02083333 Written as a percent this is 2.1 %. The calculation shows a head loss of 8.46 feet of fluid. If the percentage is less than 2 percent, you will need to regrade your yard to obtain the proper slope. Convert the rise and run to the same units and then divide the rise by the run. For instance, 3" rise divided by 36" run = .083 x 100 = an 8.3% slope. This would be the total units y for every unit x. Calculate the total slope percent using the values from step 1 and 2 along with the formula. ! Calculate the Slope. Enter the rise and run of a slope into the calculator. This equals height difference (z) between the beginning and end of the pipe (x) ⋅ (y)=(z) 3. Atlantes. Here is the Percent Slope formula: Slope = (Rise/Run)x100. Then simply multiply the decimal by 100 to find the percentage. Next, determine the run for every unit rise. Copyright 2013 | Construct Calcs, LLC (All Rights Reserved), Volume of Pipe Excavation, Bedding or Backfill with Sloped Banks, Box Culvert, Volume of Elliptical Tank with Non Domed Ends. Convert the rise and run to the same units and then divide the rise by the run. You don't need a slope percentage calculator most of the time if you already have the slope; just multiply by 100, or equivalently, and move the decimal point in the slope two places to the right. One way to express slope is as a percentage. ! To use this, you must take the required measurements so you can input them in the required fields. ! To find the percentage multiply this decimal by 100, like this: 100 × .3125 = 31.25%.

This pipe flow rate calculator calculates the volumetric flow rate (discharge rate) a gas or liquid going through a round or rectangular pipe of known dimensions with a known velocity. First, determine the rise for every unit run. When flow enters your … The calculator will evaluate and display the percent slope. ! The distance between the points is called the run. This would be the total units y for every unit x. This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent. 25 inch over a run of 12 inches so the slope is . 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. ! ! A Slope can be referred to as a piece of ground that has a specific slant, which is also called a "Grade". One way to express slope is as a percentage.
