Where's the equation relating thermal mass to temperature and heat transfer rate? Mollwollfumble (talk) 06:35, 23 June 2009 (UTC)

To those in the know, the equation is obvious from the units. For those not in the know, I've added the equation, based on the one in specific heat capacity. (Although, note that thermal mass relates temperature and heat transfer, not heat transfer rate - you may be looking for something like Newton's law of cooling, which is related to thermal conductivity.) ― Darekun (talk) 13:46, 27 July 2009 (UTC)

## Thermal flywheel effect merge

Since there hasn't been any discussion on the merge in the months since it was tagged, and Thermal flywheel effect was simply a mention of thermal mass or specific heat capacity as applied to buildings (which this article is already mostly about), I performed the merge. Most of the information there either duplicated information here or was added, but this list of relative specific heat capacities is only partially duplicated:

Materials, higher to lower "flywheel effect"

1. Packed Earth
2. Brick
3. Water
4. Hardwood lumber or timbers
5. Softwood & construction lumber
6. Steel
7. Insulation
8. Air
9. Aluminum

Now how about either a merge with heat capacity or a clearer distinction from it? This article says "Not to be confused with Heat capacity" at the top, but then immediately goes on to say that that's exactly what it's about. Not R (talk) 20:10, 2 December 2010 (UTC)

this article appears building material specific. Thermal Mass is used throughout engineering and espeically when designing ovens, heat curing systems, and cooling systems. i.e. solder reflow ovens, adhesive cure ovens, post-process cooling etc. 74.198.8.57 (talk) 18:03, 3 February 2011 (UTC)Shawn
