Construction velocity diagrams and calculate the
missing parameters for three turbine cases as
listed below:
• Case 1 Turbine, $\alpha_{c,1}$=60°, $\alpha_{w,1}$=0, $\alpha_{c,2}$=0
• Case 2 Turbine, ?=2.0, $R_n$=50%, $\alpha_{c,1}$=70°
tan $\alpha_{c,1}$ = [?/2 + (1 - $R_n$)]/?
tan $\alpha_{c,2}$ = -[?/2 - (1 - $R_n$)]/?
tan $\alpha_{w,1}$ = -[?/2 - $R_n$]/?
tan $\alpha_{w,2}$ = [?/2 + $R_n$]/?
($C_1$/u)² = [(1 - $R_n$) + ?/2]² + ?²
($C_2$/u)² = [(1 - $R_n$) - ?/2]² + ?²
($W_1$/u)² = [?/2 - $R_n$]² + ?²
($W_2$/u)² = [?/2 + $R_n$]² + ?²
