where (A) is the surface area of the plate and (Z) is the thermal conductivity of the plate and its contents, given in appropriate units.

Substituting for (dt) from equation (66),

                                                           (69)

Substituting in equation (67) for (HC) from (68) and (GC) from (69),

           

  or                (70)

    Thus,
