Change 60 percent to decimal form. Sixty percent means 60 out of 100. It can be written 60/100 = 0.60. See Chapter 1. Slope angle = inverse tan of the slope percent (in decimal) Slope angle = inverse tan of 0.60 Step 2. Enter .6 into the calculator and push the inverse, inv, or "2nd" button, then the tan button to get the inverse tangent.
WebAug 1, 2024 · In work by Nelson (1980) theoretical formulations for flame length, height, tip velocity and tilt angle as a function of Byram intensity were examined for light southern pine fuels. In addition to theoretical modeling, the work presents results from semi-empirical power-law modeling of flame length and tip velocity as a function of Byram intensity.
