Hai,

   I have a problem in solving the below problem, kindly help me.

Air is being furnished to a 30-ft by 40-ft by 12-ft room at the rate of 600cfm and mixes thoroughly with the existing air in the room before it is continuously removed at the same rate. How many times does the air change completely each hour( air changes per hour)?

600*60/(40*30*12)=2.5
