Cross Sectional Area Of Pipe

Pipe - diameter and cross sectional area

Cross Sectional inside Pipe Area

Cantankerous-sectional within area of a pipe tin be calculated every bit

A_i = π (d_i / 2)²

= π d_i ² / 4 (1)

where

A_i = cross-sectional inside expanse of pipe (mⁱⁱ, in²)

d_i = inside diameter (m, in)

Cantankerous Sectional Piping Wall Area

The cross-sectional wall area - or area of piping cloth - can be calculated equally

A_k =π (d_o / 2)^two - π (d_i / 2)²

= π (d_o ² - d_i ^two) / 4 (2)

where

A_{one thousand} = cross-sectional wall area of pipe (mⁱⁱ, in²)

d_o = outside diameter (m, in)

Weight of Empty Pipes

Weight of empty pipes per unit of measurement length can exist calculated equally

w_p =ρ_thousand A_m

= ρ_m ( π (d_o / 2)² - π (d_i / 2)ⁱⁱ)

= ρ_m π (d_o ⁱⁱ - d_i ²) / iv (three)

where

westward_p = weight of empty pipe per unit length (kg/m, lb/in)

ρ_s = density of pipe material (kg/m³, lb/in³)

Weight of Liquid in Pipes

Weight of liquid in pipes per unit of measurement length tin be calculated as

westward_l = ρ₅₀ A

= ρ₅₀ π (d_i / 2)²

= ρ_fifty π d_i ² / iv (iv)

where

west₅₀ = weight of liquid in piping per unit length of pipe (kg, lb)

ρ_l = density of liquid (kg/m³, lb/in³)

water content in pipes

Weight of Pipe filled with Liquid

Weight of piping filled with liquid per unit of measurement length can be calculated as

w = w₅₀ + w_p (v)

where

west = weight of pipe and liquid per unit of measurement length of pipe (kg, lb)

Outside Surface Surface area of Pipes

Outside surface surface area of steel pipes per unit length tin can exist calculated as

A_o = 2 π (d_o / 2)

= π d_o (half dozen)

where

A_o = outside area of pipe - per unit of measurement length of pipage (chiliad², in^two)

Inside Surface Surface area of Pipes

Inside surface area of steel pipes per unit length can be calculated as

A_i =2 π (d_i / two)

= π d_i (7)

where

A_i = inside surface area of pipe - per unit length of pipe (k², in²)
