Guest Casey Posted December 16, 2002 Share Posted December 16, 2002 Thanks guys. I found these formulas on the internet, Calculation of internal heat production, H (from McIntyre, 1980) H (W.m-2) = (M x (1- h)) x 1/AD where M = metabolic free production (W.m-2), h= mechanical efficiency and AD is the body surface area (m2). I have all of the values but I don't understand the unit.(W.m-2) (-2 is a superscript) Any help? Link to comment Share on other sites More sharing options...
Giles Posted January 9, 2003 Share Posted January 9, 2003 W is watt, i.e the unit of power (energy per unit time). I can't remember what 1W is in joules/second. m^-2 is 1/(metres squared) so it's power per unit area. Link to comment Share on other sites More sharing options...
fafalone Posted January 10, 2003 Share Posted January 10, 2003 anyone else notice how chemistry teachers seem to care alot more about units than teachers in other scientific fields, including physics? Link to comment Share on other sites More sharing options...
Sayonara Posted January 10, 2003 Share Posted January 10, 2003 That's because in physics the teachers know that if they show the class what all the units are, some bright spark will figure out they're being taught lies in preparation for college/Uni.
