When at 3.06 minutes where the formula is completed the answer is 0.157 inch but you show 0,325 inch after rounding up. So it seems there is a multiplication of 2 before rounding up is this correct? The initial calculation multiplied by 2 which equals 0.314 inch then goes to 3.25 from rounding up? Is this what you did?

@@mahmoudsalem4288 i think because he added the corrosion allowance C.A (0.125in), but why the corrosion allowance in this case equal 0.125in) !!

@@mahmoudsalem4288 my opinion is because the calculation was the minimum thickness and if seen by their planning to design, manual ->PV Elite->acad->solid (make 3d by pv elite) so in PV elite their another variable like safety factor or lifetime
