Cross Sectional inside Pipe Area
Cross-sectional inside area of a pipe can be calculated as
A = π (di / 2)2
= π di 2 / 4 (1)
where
A = cross-sectional inside area of pipe (m2, in2)
di = inside diameter (m, in)
Cross Sectional Pipe Wall Area
The cross-sectional wall area - or area of piping material - can be calculated as
Am = π (do / 2)2 - π (di / 2)2
= π (do 2 - di 2) / 4 (2)
where
Am = cross-sectional wall area of pipe (m2, in2)
do = outside diameter (m, in)
