Dear Dimitar;
Respect to the angle in Nozzle (Inyector) of Cross Flow Turbine
(alpha1), this angle is in relation with angle of the blade (beta1) for the
following relation:
Sin (Alfa1)
Beta1= ArSin ( -------------------------)
(1-3/4*(Cos Alfa1)^2)
Moreover, alpha1 is the absoluta velocity angle (C1). Considering
aspecto of manufacture (construction), is most easy Beta1=30�, then
Alpha1=16,102. If Beta1=29,99�, Alpha1=16,00�.
yours Sincerelly
