I could be wrong, but this is what I used:
1.5gallons per minute.
1.5 gallons = 5,678 milliliters = 5,678 grams
Divide by 60 for one second
= 94.6grams water / second
q=(specific heat of H20)X(grams of H20) x dT
=(4.18 J/g-K)x(94.6 grams H20)x(1K)
=395 Joules
A Joule is a watt-sec and we were measuring for one second, so that 395 watts.
And that's assuming 100% efficiency.
Probably need to go with the bigger TECs?
That seems like alot of TEC to change the water temperature though...Maybe I figured something wrong..?
