Formula for rate of heat transfer from fin - Heat Transfer

Q.  How is the rate of heat transfer from the fin given?
h = convective heat transfer coefficient
P = perimeter of the fin
k = thermal conductivity of fin
A = cross-sectional area of the fin
Ts= Base temperature of the fin
T∞ = Temperature of surrounding fluid

a. q = h P k A (Ts – T∞)
b. q = √(h P k A (Ts – T∞))
c. q = √(hPkA) (Ts – T∞)
d. none of the above

ANSWER: q = √(hPkA) (Ts – T∞)
