Like.
as far as I can tell that is what is happening. The bottom temperature is leading during the transient phase while a significant the... -
Lnewqban reacted to Ken Fabian's post in the thread Undergrad How exactly does convection motion start? with Like.
I think @Lnewqban has it right; the water at the base gets replaced rapidly and mixed with adjacent cooler water whilst the warmer water...

Lnewqban reacted to kuruman's post in the thread High School Understanding the Reasoning Behind Basic Algebra with Like.
One should not forget that algebra does not pop out of a vacuum. It is preceded by arithmetic which develops the necessary reasoning...

It's not difficult, but I do recall "getting it"(I learned algebra mostly as an adult though). I teach my kids by balance scale type...

Lnewqban replied to the thread Undergrad How exactly does convection motion start?.In addition to the excellent posts above: Ice is floating in hot water because it has no other option, it is the less dense actor in...

Did you even calculate the Rayleigh number from the page I pointed you to? How can you expect to determine things quantitatively if you...

Q‘=Q+W > Q where W is work done to the water liquid-steam system in adiabatic compression process from Figure 3 to 4 where number is...

For a meaningful comparison, one needs a controlled process. What I have in mind is the thought experiment shown on the right. Start...

You are absolutely correct. I was a bit hasty cutting and pasting labels in the figure. The original post has been edited.

Lnewqban replied to the thread Undergrad How exactly does convection motion start?.Without the energy transferred from the hot source into the cold liquid, there would not be the localized change of density; therefore...

Lnewqban replied to the thread Using the 1st law of thermodynamics to explain the change in specific latent heat.I believe that there should not be steam formation below the piston on the right when water temperature is only 100 °C. Increasing the...

Strange. Let's try it again

Lnewqban reacted to questionpanda's post in the thread Fluid dynamics with T-junction vs separate riser in tank pipe system with Like.
At jrmichler request, I have updated the diagram to include some dimensions. The original post only showed a single Source (A), however...

Lnewqban reacted to jrmichler's post in the thread Fluid dynamics with T-junction vs separate riser in tank pipe system with Like.
The inlet B with the riser will flow less than the inlet B with the T because of less restriction from elbows. If the supplementary...
