Question

he ventilating fan of the bathroom of a building has a volume flow rate of 28 L/s and runs continuously. If the density of air inside is 1.20 kg/m3, determine the mass of air vented out in one day. The mass of air is kg.

Answer 1

Answer:

$\Delta m = 2903.04 kg$

Explanation:

The mass of vented out in one day is:

$\Delta m = \rho_{air}\cdot \dot V \cdot \Delta t\\\Delta m = (1.20 \frac{kg}{m^{3}} )\cdot (28 \frac{L}{s}) \cdot (\frac{1 m^{3}}{1000 L} )\cdot (24 h)\cdot (\frac{3600 s}{1 h} ) \\\Delta m = 2903.04 kg$
