WebLaminar flows are smooth and streamlined, whereas turbulent flows are irregular and chaotic. A low Reynolds number indicates laminar flow while a high Reynolds number indicates turbulent flow. The flow behavior drastically changes if it is laminar vs. turbulent. In complex systems, the analysis of laminar and turbulent flow becomes crucial for ... Web14 hours ago · As it can be seen in the Figure at a given time heat gain increases with an increase in inlet velocity. For a given fin height the heat gain will be maximum between 12:00 to 1:00 PM. Heat gain increases as the flow velocity of duct air increases. At velocity 0.3 m/s the maximum heat gain obtained at 12:00 and i.e., approx. 84.52 W.

Flow vs Velocity. What
