Area triangles

Triangle area is Vibh where b is the base and h is the height. 

For triangular-type sieve tray pitch, use Eq. (3.98) to calculate a single triangular tray deck area, noted as SECTAREA. Each leg of the triangle is an equal pitch measure. One triangle area is equal to SECTAREA in ft2. 

Note that each triangle area contains one-half of a single hole area, which is the basis of Eq. (3.100). For square pitch, use Eq. (3.101) ... 

Using these three parameters the carbonizing materials or the carbonizing part of the initial material can be characterized in any reaction state by a point laying on the triangle area A-B-C in Figure 6. 

Gilli s correlation. The most interesting cases, with relatively long N —bonds and Xn = 0, are enclosed in the triangle area within the limits 1.38 A < < 1.47 A,... 

Integrating over the triangle area leads to the expression of as a function of x (see Figure 4.14), and therefore to its maximmn value between -Xn and Xp.
