Fin Surface Area Equation
I posted this last night, but it appears to have vanished. It's never as good the second time around...
I generated a fin surface area equation based on depth and length measurements. I used a 2016 Radar fin since I had one laying around and it seemed like a good industry standard shape. The equation obviously only holds for this fin shape, but it should hold good for the trends for any similarly shaped fin. I digitized the fin and used CAD to make the length and depth adjustments. The fin holes are accounted for. The equation is based on a simple linear regression model, which fit the measured data extremely well.
Surface Area = (2.697 * Length) + (4.841 * Depth) - 18.924
The equation fits the measured data with an R-Squared value of 0.999.
Here's the data out of CAD:
Here's the same data in graphical form along with the predicted values from the equation. The measured values are the points, the predicted values are the lines.
Not sure how to deal with a long link?
