I Forced convection over a cylinder

AI Thread Summary
The discussion focuses on measuring the effect of fluid speed on heat transfer from a solid to a fluid flowing over a cylinder maintained at a constant temperature. The user seeks to determine if the correlation between the Nusselt number and Reynolds number, typically used for flat plates, can be applied to cylinders. They reference specific coefficients for laminar and turbulent boundary layers to support their inquiry. The main concern is the applicability of flat plate calculations to cylindrical surfaces. The thread invites insights on the validity of using these correlations for their experimental setup.

I am building an apparatus to measure how does fluid speed effect heat transfer from solid on fluid. fluid runs over a cylinder which inner side is kept at a constant temperature. A calculation for surface temperature profile was made for a similar eaxperiment were a flat plate was used instead of a cylinder. I would like to ask weather it is safe to use the same correlation between the nuslet number and reynolds number:
Nu=C/m * Re˘m * Pr˘n
where C = 0.332, m = 1/2 and n = 1/3 for a laminar boundary layer
and C = 0.0287, m = 4/5, n = 3/5 for a turbulent boundary layer
and therefore if calculations for surface temperature profile calculations made for flat plate alo apply for cylinder.
Thank you for your answers

Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
