The electronic components of a computer are cooled by air flowing through a fan mounted at the inlet of the electronic enclosure. At steady state, air enters at 18oC, 1 atm. For noise control, the velocity of the entering air cannot exceed 0.9 m/s. For temperature control, the temperature of the air at the exit cannot exceed 34oC. The electronic components and fan receive, respectively, 68 W and 12 W of electric power. Determine the smallest fan area, in cm^2 , for which the limits on the entering air velocity and exit air temperature are met.
