Nusselt Number for Flat Plate: Laminar vs Turbulent

AI Thread Summary
The Nusselt number for a flat plate varies between laminar and turbulent flow, requiring distinct equations for each regime. The choice of equation depends on the flow conditions, specifically the Reynolds number. Empirical relations for Nusselt number are only valid within certain ranges of Reynolds numbers. Understanding these ranges is crucial for accurate calculations. Proper application of these equations ensures accurate thermal analysis in fluid dynamics.

The Nusselt number for an entire flat plate in the turbulent region has two different equations: One for Turbulent and one for Combined Laminar and Turbulent. How do I know when to use one or the other?

Those empirical relations generally have a range of Reynolds number in which they are valid. It's likely they are different.
 
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...
