Question about sizing roof drain and down spout for a flat roof 1/4" to 12" slope. This roof is in the Hampton, Newport News Area, Va. The area rain fall intensity by code is 3.5-inches per hour. Does anyone have a spread sheet or long-hand calc's that I could use?
Question in calculating electrical load drop (if any) in a 110/120 circuit running a distance of 100-feet. This line may have 5 duplex outlets. Any idea on to figure this or point me in the right direction.
Thanks,
Scott
