Ответ:
Yes, fan will provide enough airflow in the ranger station.
Step-by-step explanation:
A ranger station consist of a rectangular pyramid and a rectangular prism.
So volume of air in ranger station = volume of prism + volume of a pyramid
Volume of a rectangular prism = Length×Width×height
= 10×8×8 = 640 ft³
Volume of the pyramid =
=
= 80 ft³
Total volume of the ranger station = 640 + 80 = 720 ft³
Since CFM has the airflow capacity of 1500 cubic feet per minute so one CFM will be sufficient for the volume of 720 ft³.
