Air is flowing steadily over a series of turning vanes. The vanes are spaced 15 cm apart and arranged periodically, so identical control volumes can be drawn around each vane as shown in the figure. (the entry and exit planes are vertical). Air enters the control volumes at a uniform velocity of 15 m/s and an average gauge pressure of 60 Pa. Air leaves the control volume with a uniform velocity ₂ and a gauge pressure of 0 Pa. Pressure forces on the other surfaces will cancel due to the periodic arrangement of the vanes and do not need to be considered. The turning angle is 30°. Use a constant air density of 1.225 kg/m³ in your analysis, i.e. assume incompressible flow. Also, gravity may be neglected. (a) Using the continuity equation, find an expression for the vector velocity at the exit, ₂. (b) What are the lift and drag forces (per unit span) acting on each turning vane? Note, the lift and drag are directly related, but not equal to the vector F representing the force acting on the fluid, due to the vane.

Select the correct statements regarding the addition of moments. (Select 3) Moments have directions, so a negative value implies it is along the opposite direction from the reference direction. All the moments need to have the same reference point/pivot in order to add together. Calculate each moment by multiplying each force with its distance to the reference point, and add all values together, regardless of their direction. You have to define the reference direction first, either clockwise or counter-clockwise.
