Re: [Amps] Advice needed for SS amp

[Larry Benko <xxw0qe@comcast.net>]

2000W of power(heat) into 1 gallon of pure water raises the temperature 
7.7deg. C (13.7deg. F) per minute.  Anything you do to water such as 
mixing in alcohol reduces the cooling capacity somewhat.  In a total 
loss system where the water would be run through the amp and then out 
into the garden a flow of 1 quart (or ~ 1 liter) per minute would suffice.
