pipe surface area

Outside Surface Area of Pipes

Outside surface area of steel pipes can be calculated as

A_o = 0.2618 d_o (4)

where

A_o = outside area of pipe - per foot (Square Feet)

d_o = outside diameter (inches)

Inside Surface Area of Pipes

Inside surface area of steel pipes can be calculated as

A_i = 0.2618 d_i (5)

where

A_i = inside area of pipe - per foot (Square Feet)

d_i = inside diameter (inches)

Area of the Metal

Area of the metal can be calculated as

A_m = 0.785 (d_o ² - d_i ²) (6)

where

A_m = area of the metal (Square inches)

d_i = inside diameter (inches)

d_o = outside diameter (inches)
