The genereal concensus was:
BTU/hr = 3.4 x power in watts
6000BTU =~ 1 Ton of cooling =~ 1764.7 watts or 1.7647kW
But, a more accurate calculation came from Douglas Palmer (Where did
that tag line come from?):
number of watts total / (3/4) * 3.41 to get total BTUs
two systems with dual 300 watt power supplies
and no monitors =
2 x 2 x 300 x 1.33 x 3.41 = 5456 BTUs
The 1.33 is for efficiency -- no power supply is
100% efficient. 3.41 is
the conversion from watts to BTU.
Other suggestions included looking in the manuals or sundocs to find
listing for heat genereation. While this is true, I have a lot of
equipment wqhich is non-Sun and also nobody can find the documentation
or the manufacturer has gone out of business.
Thanks again to all those who replied. I would name them all, but there
are just too many. It's good to see that in the SysAdmin community,
there are those who are willing to share information and experience....
