WebDownload Schedule 40 Steel Pipe Velocity diagram as pdf file; SI units. Fluid flow velocity in a circular pipe can be calculated with SI units as. v = 1.273 q / d 2 (2) where . v = velocity (m/s) q = volume flow (m 3 /s) d = … WebAlthough the gas velocity reaches a maximum and becomes choked, the mass flow rate is not choked. The mass flow rate can still be increased if the upstream pressure is increased as this increases the density of the gas entering the orifice. The value of Cd{\displaystyle C_{d}}can be calculated using the below expression:
