The length LDE is from Figure 1a equal to B/2sin β/tan α; from Figure 1b VDE = VBDE = Vf/sin β, and CUIDE is given from Equation 3 with the angle iDE equal to π/2-β+Ψ.
La longitud LDE proviene de la Figura 1a, igual a B/2sen β/tan α; de la Figura 1b VDE = VBDE =Cui, y CuiDE se da a partir de la Ecuación N° 3 con el ángulo iDE igual a π/2-β+Ψ.
