(1) Nominal Diameter according to DIN EN ISO 6708
(2) Pressure loss ratio of laminar flow in two straight pipes with consequent nominal diameters. At turbulent flow savings in pressure loss will outrange those of laminar flow.
(3) Density of steel: 7850 kg/m³
(4) bend type A: inner diameter bend = inner diameter pipe
