All of these conditions should all be taken into account when calculating mix design.
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.
For the vast majority of tank based rainwater harvesting systems the catchment area is the roof surface.
There are some important factors about the roof to consider when planning for a rwh system.
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.
Why is the calculation for the surface area of a domed tank less than the surface area of a flat top tank.
Roof material the material of the roof is not as important as contaminants that may be on the roof.

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.
The information generated by the dalton coatings calculators is for estimating purposes only.
The surface area of a rectangular tank is the sum of the area of each of its faces.
