Great! Thank you so much, Esstee!

Maybe I should learn how to calculate the run time. Let's start with the total wetted area. Please verify my formulas.

D = Diameter of coin = 39.97 mm
T = Thickness of coin = 3.29 mm
d = diameter of 14 AWG wire = 1.63 mm
l = length of 14 AWG wire submerged in water = 1.25" = 31.75 mm

Wetted area of coin = (Pi x D^2 / 4) x 2 + Pi x D x T
= Pi x D^2 / 2 + Pi x D x T
= Pi x (D^2 / 2 + D x T)
= 3.1416 x (39.97^2 / 2 + 39.97 x 3.29)
= 2922.64 mm2

Wetted area of 14 AWG wire = Pi x d x l + pi x d^2 / 4
= Pi x (d x l + d^2 / 4)
= 3.1416 x (1.63 x 31.75 + 1.63^2 / 4)
= 164.67 mm2

Total wetted area = 2922.64 + 164.67
= 3087.31 mm2

That's about all I know how to calculate. ;)

Could you please give me the formula for the rest of the calculations?

Thanks again!
