Cross Sectional Area Pipe Calculator
With this online calculator you can calculate the cross-sectional area of a pipe.
Formula:
S = π D2 / 4 - π d2 / 4
S - cross sectional area pipe
D - outer pipe diameter
d - internal pipe diameter
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow.
