Question 11
11.
For health reasons air conditioning systems are designed to exchange the air in a room every 6 to 10 minutes. An air conditioner that has a mass flow rate of 14.6 kg/min circulates the air in a classroom of size 6m x 6m x 2.5 m. The air has a mass density of 1.2 kg/m3
This means that each of the cubic meters calculated will have 1.2 kg of air in them.
B) What is the MASS OF AIR in the room?
