The formula is Kelvin's : I.29 Page 12.
There's a critical radius value, below which drops will shrink, above which
they'll grow.
I don't know if my mis-remembered C-name was Critical, Kelvin or a nearby
Clapeyron equation.
Anyway , now I can finish reading
There's also a Clausius-Clapeyron equation.
(There's probably a single neuron in my brain recording that C memory.

Rossi always uses the input flow rate to calculate the output power, so he

He always assumes this equals the input mass flow and it is all vaporized.
From this assumption he calculates the output energy.
