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
