– Velocity Magnitude 5m/s ,Turbulent Intensity, 5% ,Hydraulic Diameter, 0.15m Temperature 10°C Inlet flows bring turbulence with them. The quantities depend on the upstream conditions so they are user inputs. For flow in pipes turbulentpipes, ,turbulent intensity, is typically 5 to 10%. The length-scale of the turbulence can be deduced from the
