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
 
Engineering news on Phys.org


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?

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
