A compressor cascade has an inlet flow velocity V$1=149$ m$/$s at an angle of $1=49$ and an exit flow velocity V$2=113$ m$/$s at an angle of $2=29.$ A$)$ Calculate the De Haller numberB$)$ Calculate pitch$-$to$-$chord ratio $($s$/$l$)$ C$)$ Discuss the design feasibility of the cascade based on your calculated Dehaller Number. Note: diffusion factor is DF$=0\mathrm{.}4$
