WebIf you don't have a velocity by which to calculate the Reynolds Number, you will need to assume either a velocity or an initial friction factor. If you assume an initial velocity, proceed as usual. If you assume a friction factor (I like 0.02), jump to step 10. If done correctly, you will converge on the same answer. Refer to the Moody Chart. WebWhich friction factor is plotted in a Moody diagram may be determined by inspection if the publisher did not include the formula described above: Observe the value of the friction factor for laminar flow at a Reynolds number of 1000. If the value of the friction factor is 0.064, then the Darcy friction factor is plotted in the Moody diagram.
WebThe friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against the Reynold's number. The blue lines plot the friction factor for flow in the wholly turbulent region of the chart, while the … WebReynolds number greater than 4000 indicates turbulent flow, while Reynolds number less than approximately 2000 indicates laminar flow. Once the Reynolds number and …
WebThe Reynolds number for a pipe or duct expressed in Imperial units. Re = 7745.8 u dh / ν (2a) where. Re = Reynolds Number (non dimensional) u = velocity (ft/s) dh = hydraulic diameter (in) ν = kinematic viscosity (cSt) (1 cSt = 10-6 m2/s ) The Reynolds Number can be used to determine if flow is laminar, transient or turbulent. The flow is. WebBesides, the resemblance in average Nusselt number and friction factor are presented. To grasp the effectiveness of heat transfer, thermal efficiency has been calculated to find the optimum condition, and it reveals that the critical corrugation height, h = 0.0318 D at Re τ = 314, f c = 18, φ = 2% corresponds to higher thermal efficiency.
