The angle of incline can also be expressed in other units of angle measurement, such as radians or grads. The following formula is used to calculate the percentage of a slope of a line with respect to rise over run. ! b) To determine the pipe slope, subtract the two manhole inverts and divide the difference by the pipe distance and multiply by one hundred (100) to obtain the percent grade of the pipe. As a general rule, the recommended slope for most plumbing pipes is 1/4 inch vertical drop over every 1 horizontal foot, or about 2 percent. The difference in elevation between points is called the rise. Calculate the total slope percent using the values from step 1 and 2 along with the formula. One way to express slope is as a percentage. Slope percentage is calculated in much the same way as the gradient. That means for a run of pipe of a certain length the rise must be 0.01 times the length. To use this, you must take the required measurements so you can input them in the required fields. Simply enter in … ! If the percentage is less than 2 percent, you will need to regrade your yard to obtain the proper slope. In your example the rise is . According to plumbing code, drain pipe has to be sloped a minimum of 1/4-inch per foot and a maximum of three inches per foot or vertical.
