WELLS Turbine Design Help - Tips for Solving Problems and Calculations

WELLS Turbine design! URGENT!

Hello, PLEASE CAN ANYBODY HELP ME!? I am student of Mechanical engineering and I have to solve some problems regarding the WELLS TURBINE DESIGN! Does anyone have any links regarding this topic?

And also could anybody help me out with this? I would be very very grateful! (Maths is not my biggest strength :)

1.How do you get the value U if alpha is in degrees and beta is pi/2
cot α1 = U/VX1 – cot β1
α1 = 90°
β1 = Π/2
VX1 = 265

2.How do you calculate the values for Cθ and Cx based on the differentiation equation?
dFθ = Cθ 550 dr
dFx = Cx 850 dr

β1 = Π/2

Π/2 = 90°

If that helps at all.

Hello, thanks so much for the reply!

Do you maybe know about

NACA 0012

and how you get the alpha value?
