A desktop computer is to be cooled by a fan. The electronic components of the computer consume 60 W of power under full-load conditions. The computer is allowed to operate in adiabatic environments at T up to 45C and at elevations up to 3400 m where the average Patm is 66.63 kPa. For reliability requirement, the exit T of air must not exceed 60C while the average velocity of air must not exceed 110 m/min at the exit of the computer case where the fan is installed to keep the noise level down. Compute the required volumetric flow rate of air and the diameter of the casing of the fan. T2 P2 T1 Y Wein Wfan,in
