Question

The ventilating fan of the bathroom has a volumetric flow rate of 1,901 L/s. If the air density is 1.23 kg/m3, calculate the mass flow rate of air in kg/h

Answer 1

Answer:

$\dot m_{air} = 8417.628\,\frac{kg}{h}$

Explanation:

Mass flow rate of air is:

$\dot m _{air} = \rho_{air}\cdot \dot V_{fan}$

$\dot m_{air} = (1.23\,\frac{kg}{m^{3}})\cdot (1901\,\frac{L}{s} )\cdot (\frac{1\,m^{3}}{1000\,L} )\cdot (\frac{3600\,s}{1\,h} )$

$\dot m_{air} = 8417.628\,\frac{kg}{h}$
