I am working on a Hesston baler that has a floating orifice in the tailgate hydraulics. You can use a .960" or an .080" orifice. I am trying to figure how much more (in percent) the larger one will flow.
I know that the formula for the area of a circle is pi times the square of the radius. What is confusing me is that usually when you square a number, you end up with more; i.e.- 4 x 4= 16. A larger number than you started with. When you square a decimal(the radius of .080 is .040), you end up with a number that is less than what you started with. .040x.040=.0016.
Is this going to work in figuring the area of the .080" circle? .0016x3.1416=.005026 sq. inch. Is that the area of the .080" circle?
