Answer:
[tex]\dot m_{air} = 8417.628\,\frac{kg}{h}[/tex]
Explanation:
Mass flow rate of air is:
[tex]\dot m _{air} = \rho_{air}\cdot \dot V_{fan}[/tex]
[tex]\dot m_{air} = (1.23\,\frac{kg}{m^{3}})\cdot (1901\,\frac{L}{s} )\cdot (\frac{1\,m^{3}}{1000\,L} )\cdot (\frac{3600\,s}{1\,h} )[/tex]
[tex]\dot m_{air} = 8417.628\,\frac{kg}{h}[/tex]
