Hello,
I am trying to figure out the capacity of my dryer. I need to know the size in order to buy a new one. The drum within measures 27” in diameter and 18” deep. I know that I am looking for an answer in cubic feet but am not sure how to determine this. I would appreciate your help.
Thank you.
Darlene
Hi Darlene,
The shape of the drum in your dryer is a circular cylinder, and the volume of a cylinder is
volume = (area of the base)
(height)
Since the base of your cylinder is a circle the volume is
volume =
where is approximately 3.1416. The drum radius for your dryer is 27/2 = 13.5 inches.
Since you want the volume in cubic feet I think it is best to change all the measurements to feet before you calculate the volume. The height is 18 inches which is 18/12 = 1.5 feet. The radius is 13.5/12 = 1.125 feet. Thus the volume is
volume =
