WebTable 10-4 to determine the Reynolds number and in turn the Nusselt number. In all cases the fluid properties are evaluated at the mean fluid temperature given as T mean = 1 2 (T m,in +T m,out) except for μ w which is evaluated at the wall temperature, T w. 2. Turbulent Flow in Circular Tubes, Isothermal (UWT) and Isoflux (UWF) For ... WebThe accepted transition Reynolds number for flow in a circular pipe is Re d,crit = 2300. Transitional flow. At Reynolds numbers between about 2000 and 4000, the flow is unstable due to the onset of turbulence. These flows are sometimes referred to as transitional flows. Turbulent flow. If the Reynolds number is greater than 3500, the flow is ...
