I removed an external link to a users personal webpage. It was only loosely related to the article, and did not add any relevant information that was not already here. Djd sd (talk) 01:54, 28 January 2008 (UTC)Reply

I removed the link again and also removed the table. The table of prandtl number vs. temperature for air, in my opinion, does not add to the article. The article already states the prandtl number of air pretty closely. Also, if we put a table for air, then we'd have to put tables for all kinds of fluids.Djd sd (talk) 05:23, 30 January 2008 (UTC)Reply

I seems to me that the phrase: "heat diffuses very quickly compared to the velocity (momentum). This means that for liquid metals the thickness of the thermal boundary layer is much bigger than the velocity boundary layer." is misleading. If heat diffuses quickly relative to the change in velocity, the thermal boundary layer should be thinner than the momentum boundary layer.132.66.52.193 (talk) 06:54, 23 August 2011 (UTC)Reply

^ Agreed.

Small and large values of the Prandtl numbers and how they relate to thermal/momentum diffusivity should be sourced Rmason81 (talk) 04:22, 13 January 2017 (UTC)Reply
The prandtl number values may look neater compiled into a table. Applications of the prandtl could be explored. Needs more than one source. Forbisl (talk) 04:36, 13 January 2017 (UTC)Reply
