Question: (i) (iii) A two-throat wind tunnel is designed with area ratios as shown. With the calculations, determine if the tunnel will start or not.

(i) (iii) A two-throat wind tunnel is designed with area ratios as shown. With the calculations, determine if the tunnel will start or not. (8 points) If the back pressure can be lowered to any value (while P01 is held constant) then what is the maximum Mach number that can be achieved in the test section? (6 points) If P01-10 atm and the back pressure is brought to a very low value (near vacuum), then determine the pressure at the exit of the diffuser (section 'd') (6 points) Ats=5At1 Ad=5At1 At1 At2=2A+1 P01 Test section Pb Diffuser, 'd'
