The ventilation fan of the bathroom has a volumetric flow rate of 1,640 L/s. If the air density is 1.28 kg/m3, calculate the mass flow rate of air in kg/h

7557120 kg/hour

Explanation:

Given data;

Volume of air in one second = 1640 L

Density of air = 1.28 kg/L

Mass of air in 1 hour =?

Since mass = density × volume

==> Mass of air in one second = 1.28 ×1640 = 2099.2 kg

==> Mass of air in one minute = 2099.2×60=125952 kg

==> Mass of air in one hour = 125952× 60 = 7557120 kg

So rate of flow of air is 7557120 kg/hour

technology is the application of the knowledge gained by science.
