Well, blighmy, blow me
down. Who woulda thunk? Thanks Ed. Just for fun, maybe we
should all start start measuring our heat in Stone*Furlongs.
Excellent! Or perhaps the power of our 13B's as Stone Furlongs/ hour
glass. Just to sound like we have been doing this since they built stone
hinge. :)
BTW, 10 deg delta seems
about right judging by the typically slow rate of rise of our water
temperatures. If there were a 100 deg delta, I would expect coolant to hit
200 shortly after take off. Instead, it takes a good 20 min to settle in,
even at climb power.

Right you are, Dave
Below is one semi-official definition of BTU
in English units. 1 BTU is amount of heat to raise 1 lb of water 1
degree Fahrenheit.
So with Tracy's 30 gpm flow of water = 240
lbs/min. Since its temperature is raised 10 degree F we
have
BTU = 240 * 10 * 1 = 2400 BTU/min
I know I'm ancient and I should move into the
new metric world, but at least I didn't do it in Stones and Furlongs
