DERIVATION Of D2/162 For Calculating Steel :- This is very useful formula for calculating steel , In every construction work at site that requires steel this formula can be used for calculating steel .We know the formula D 2 /162 which is being used for calculate unit weight of reinforcement per meter.Here we are willing to explain how it has been arrived D2/162 (Note: D unit is in MM)
Weight of bar per meter = Area of steel bar X Density of steel x Length of bar
= (3.14 x D2/4) x 7850 kg/m3 x 1 m= D2 X 6162.25/(1000x1000)= D2 X (0.006162)= D2 X 1/(0.006162)-1= (D2/162.28)
The actual value is D2/162.28
Kindly note that this function is only applicable for circular shape steel which density is 7850kg/m3
