Question

3. The electronic components of a computer consume 0.1 kW of electrical power. To prevent overheating, cooling air is supplied by a 25 W fan mounted at the inlet of the

electronics enclosure. At steady state, air enters the fan at 20°C, 1 bar and exits the electronics enclosure at 35°C. There is no significant energy transfer by heat from the outer surface of the enclosure to the surroundings and the effects of kinetic and potential energy can be ignored. Determine the volumetric flow rate of the entering air, in m³/s.
