Why round bar number calculator with same area in a same width, different dia and numbers need?
Some times a particular dia of steel not available at site, hence we have to change with the adjacent dia of steel, so new bar number will change. Round bar number calculator calculates the different dia numbers.
What is the round bar number calculator with same area in a same width, different dia and numbers formula?
d1= Round bar-1 dia
n1= Round bar-1 number
d2= Round bar-2 dia
Let round bar-2 number, n2
For same area of round bar in particular breadth (b) of any structure-
Area-1 = Area-2
(π*d1^2*b*n1)/(4) = (π*d2^2*b*n2)/(4)
(d1^2)*(n1) = (d2^2)*(n2)
n2 = (d1/d2)^2*n1)
