<---------------- Tinf (Air Flow)
_________T2________

-------------------------------
Tp
Rotor Side

(K(Tp-T2))/t = h(T2-Tinf)

Again, you would have to know the temp of the pad closest to the air flow....

Solving for Tp.....

Tp = (ht(T2-Tinf)+T2)/k

On the flip side, if you know how much heat is generated (from where you convert kinetic to thermal energy, friction b/t pad and rotor), and you know the temp of the pad on the piston side, you can use:

q = (k(Tp-T2))/t.....where q is the heat generated from kinetic to thermal energy.

Either way, you're gonna have to get some sample temps or assume temperatures.
