a) the total roof area b) the approximate drain diameter you will use Note: When determining the nuer roof drains required recognize that the smaller the roof drain outlet diameter the more drains you will need. Conversely, the larger the drain outlet diameter the fewer you will need. How to calculate the quantity of drains required: 1.)

Selecting the Optimum Pipe Size

Early pipe size selection was simple. The original pipe fabriors/layers of old were for the most part, not concerned with determining optimum pipe sizes since mere tier availability dictated the diameters installed. Selecting the Optimum Pipe Size 2

APPENDIX A ROOF DRAIN SIZING METHOD - eCodes

A 5-inch diameter pipe with a 1/4 inch per foot slope will carry 4,720 sq ft. A minimum 5-inch diameter drain on a 1/4 inch per foot slope is required. Step 5. Horizontal Drain 10,000 sq ft. To convert to an area for use in Table 1108.2 do this: RD RD 10,000 ÷ 4 x 3.75 = 9,375 sq ft. Enter Table 1108.2 until you find a diameter pipe that will
