Given;
External Diameter (D) =150mm = 0.15m
Internal Diameter (d) =140mm = 0.14m
Thickness of pipe =10mm
Length of pipe (L) =1m
Density of Steel = 7850 kg/m3
To calculate the weight of hollow steel pipe we have to apply following formula;
WEIGHT = VOLUME x DENSITY OF STEEL
First of all we calculate the volume
Volume = { Area x Length}
= { 𝝅/4 (D^2 - d^2) } x Length
= {3.14/4 (0.15)^2 - (0.14)^2 } x 1
= 0.002276 cum
Now we have the volume = 0.002276 cum
Put this volume value in weight formula
Weight = Volume x Density of steel
= 0.002276 m3 x 7850 kg/m3
= 17.87 kg.
Hence 17.87 kg is the weight of 1m size steel hollow pipe whose external dia = 150mm & internal dia = 140mm.
External Diameter (D) =150mm = 0.15m
Internal Diameter (d) =140mm = 0.14m
Thickness of pipe =10mm
Length of pipe (L) =1m
Density of Steel = 7850 kg/m3
To calculate the weight of hollow steel pipe we have to apply following formula;
WEIGHT = VOLUME x DENSITY OF STEEL
First of all we calculate the volume
Volume = { Area x Length}
= { 𝝅/4 (D^2 - d^2) } x Length
= {3.14/4 (0.15)^2 - (0.14)^2 } x 1
= 0.002276 cum
Now we have the volume = 0.002276 cum
Put this volume value in weight formula
Weight = Volume x Density of steel
= 0.002276 m3 x 7850 kg/m3
= 17.87 kg.
Hence 17.87 kg is the weight of 1m size steel hollow pipe whose external dia = 150mm & internal dia = 140mm.
