Weight of water in pipes filled with water can be calculated as
ww = 0.3405 di 2 (3)
where
ww = weight of steel pipe filled with water (Pounds per Foot Pipe)
di = inside diameter (inches)
Weight of Empty Steel Pipes
Weight of empty steel pipes can be calculated in imperial units as
wp = 10.6802 t (do – t) (2)
where
wp =weight of steel pipe (Pounds per Foot Pipe)
t = pipe wall thickness (Inches)
do = outside diameter (inches)
Or. alternatively in metric units
wp = 0.02464 t (do – t) (2b)
where
wp =weight of steel pipe (kg/m)
t = pipe wall thickness (mm)
do = outside diameter (mm)
Cross Sectional Area
Cross-sectional Area of a Steel Pipe can be calculated as
A = 0.785 di 2 (1)
where
A = cross-sectional area of pipe (Square Inches)
di = inside diameter (inches)
