BARLOW'S FORMULA FOR CALCULATING BURSTING PRESSURE :
P = 2ST/D or t-DP/2S or S-DP/2t or D = 2st/P.
P = Bursting Pressure P sil
S = Tensile Strength of tube
T = Wall thickness (In Inches)
D = Outside diameter (In Inches)
-
FORMULA FOR CALCULATING PIPE WEIGHT :
Od minus wall thickness X wall thickness X 0.00756 = weight of pipe per foot (All in mm)
-
FORMULA FOR CALCULATING SHEET WEIGHT :
Thickness (mm) C width (Ft.) X length (Ft.) 3/4" = weight (kg per sheet)
Thickness (mm) X Length (meter) X Width (meter) X 8 - Kg per sheet
-
FORMULA FOR CALCULATING ROUND BAR WEIGHT :
Dia (mm) X Dia (mm) X 0.0019 = Weight (Kg per foot)
-
FORMULA FOR MAKING TUBES FRO SHEET :
(Outer Dia - Wall Thickness) X 22/7 - Width of sheet
-
FORMULA FOR CALCULATING HEXAGONE BAR WEIGHT :
OD X OD X 0.002072 = Weight per foot (All in mm)
-
FORMULA FOR CALCULATING SQUARE BAR WEIGHT :
OD X OD X 0.0024 = Weight per foot (All in mm)
-
FORMULA FOR CALCULATING CIRCLE WEIGHT :
A. dia x dia x Thickness /160 = grams Per pc.
B. Dia (mm) x DIA (mm) X Thickness (mm) X 0.0000063 Kg. Per Pc.
