Some thermal data

This file contains some data for chapter VIII,The mathematics of hot rods , of Harrell and Herod's WWW textbook

Here are some approximate physical data, from sources including the CRC Handbook of Chemistry and Physics, 48th ed., Cleveland: Chemical Rubber Company, 1967, and E.S. Dana and W.E. Ford, Textbook of Mineralogy, New York: Wiley, 1964. These characteristics actually depend on such factors as temperature and pressure. According to the Dulong-Petit law, the specific heat capacity of an element is roughly inversely proportional to its atomic weight, but there is no simple rule for solid compounds. These data should not be regarded as accurate (send corections).

Heat constants for common materials
sigma rho kappas k
units cal/(hr-cm-deg) gm/cm3 cal/(gm-deg) cm2/hr
glass 80 2.8 .2 (guess) 140
iron 6800 7.9 .1 8600
granite 300 2.7 .19 (orthoclase) 585
water 5 1 1 (or .5 for ice) 5
wood 350 .7 .2 (guess) 2500
air . 002 .0011 .25 (N2) 7
