The Biot number (Bi) is the dimensionless parameter describing if the temperature of an object will vary significantly in space. It depends on the following quantities:

h = heat transfer coefficient [=] W/(m2 °C)

LC = characteristic length = Volume of object>Surface Area of object [=] m3/m2 = mk = thermal conductivity [=] W/(m K)

Use your knowledge of dimensions to determine the proper form of the Biot number.

(A) Bi =

(B) Bi = h Lc k

(C) Bi =

(D) Bi =
