      Hi Sir,

      In the External natural convection video, Natural convection course the instructor is saying that "In turbulent flow, the HTC is independent to body characteristic length" (PFA)

      Hello It is the Nusselt number which is linearly proportional, not HTC. To obtain HTC, you will need to use the definition of Nu number. The L in the Nusselt number definition and L on the RHS will cancel and you will observe that HTC is actually independent of the length scale.

      Thank you, very much sir. Understood mathematically any physical reason why in turbulent flow HTC doesn't depend on characteristic length? TIA
