How to calculate the pipe diameter, such as 200 cubic meters of water per hour. How to calculate the formula
Pipe diameter d = √ [4 flow D / (π economic velocity V)]
Among them: pipe diameter D is in meter, economic flow velocity V: 1.2m/s for pipes below DN300 and 1.5m/s for pipes above DN300; flow unit is m3 / s
Therefore, pipe diameter d = √ [4x (200 / 3600) / (π x1.2)] = 0.243 (m) = 243mm
