The case of a power transistor, which is of length L = 10 mm and diameter D = 12 mm, is cooled by an air stream of temperature T∞ = 25°C as shown in Fig. P15.6.

Under conditions for which the air maintains an average convection coefficient of on the surface of the case, what is the maximum allowable power dissipation P_e if the surface temperature T_s is not to exceed 85°C?
