Question: A desktop computer is to be cooled by a fan whose flow rate is (0.30 mathrm{~m}^{3} / mathrm{min}). Determine the mass flow rate of air

A desktop computer is to be cooled by a fan whose flow rate is $0.30 \mathrm{~m}^{3} / \mathrm{min}$. Determine the mass flow rate of air through the fan at an elevation of $3400 \mathrm{~m}$ where the air density is $0.7 \mathrm{~kg} / \mathrm{m}^{3}$. Also, if the average velocity of air is not to exceed $95 \mathrm{~m} / \mathrm{min}$, determine the minimum diameter of the casing of the fan. Answers: $0.00350 \mathrm{~kg} / \mathrm{s}, 0.0634 \mathrm{~m}$
