i want to make a program that realistically boils water with all the variables but know near nothing about the math
i got the energy transfer equation down
but this seems to be giving me some trouble or more specifically the "convective heat transfer coefficient" http://www.engineeringtoolbox.com/convective-heat-transfer-d_430.html
i would assume i would use this http://www.engineeringtoolbox.com/overall-heat-transfer-coefficient-d_434.html but i dont understand how to use the formula
like is it "1 / U (A) = what ever" or "(1 / U A) = what ever" and what are the little down numbers on A and h?
