A desktop computer is to be cooled by a fan. The electronic components of the computer consume 80 W of power under full-load conditions. The computer is to operate in environments at temperatures up to 50°C and at elevations up to 3000 m where the atmospheric pressure is 70.12 kPa. The exit temperature of air is not to exceed 60°C to meet the reliability requirements. Also, the average velocity of air is not to exceed 120 m/min at the exit of the computer case, where the fan is installed to keep the noise level down. Specify the flow rate of the fan that needs to be installed and the diameter of the casing of the fan.

Question
A desktop computer is to be cooled by a fan. The electronic
components of the computer consume 80 W of power under
full-load conditions. The computer is to operate in environments
at temperatures up to 50°C and at elevations up to 3000 m where
the atmospheric pressure is 70.12 kPa. The exit temperature of air
is not to exceed 60°C to meet the reliability requirements. Also,
the average velocity of air is not to exceed 120 m/min at the exit
of the computer case, where the fan is installed to keep the noise
level down. Specify the flow rate of the fan that needs to be installed
and the diameter of the casing of the fan.
