Surface area of tank roof.

This is an important figure to understand so you can design a rain harvesting system and choose a tank size that will meet your water volume requirements. Conditions that affect the outcome of a job include but are not limited to. Annual rainfall in millimetres x roof surface area in square metres roof catchment capacity. For landscape purposes the common asphalt shingle will work fine.

There are some important factors about the roof to consider when planning for a rwh system. Below are the formulas for cone and dome roof areas. Surface area of cone π r s surface area of dome 2 π r h height of dome h rr r r radius of tank s slant height of cone rr dome radius cone roof is specified by angle with horizontal whereas dome roof is specified by dome radius. Sa 2lw 2lh 2wh.

Total sa 2π 3 5 3 5 5 5 197 920 ft 2. Using domed tank formula 2 pi r r r dome ht works out to be less surface area than a flat top tank area formula pi r x r shouldn t the dome have more surface area than the flat surface. Why is the calculation for the surface area of a domed tank less than the surface area of a flat top tank. For the vast majority of tank based rainwater harvesting systems the catchment area is the roof surface.

The information generated by the dalton coatings calculators is for estimating purposes only. Roof material the material of the roof is not as important as contaminants that may be on the roof.
