Question:

In problem 15-2-30[BIO], determine the air speed below which flow bypass is not necessary.
Problem 15-2-30
A symmetric converging diverging duct with an area ratio of 2 is placed in a wind tunnel where it encounters a 300 m/s flow of air at 50 kPa, 300 K. Determine the bypass ratio (diverted flow / incoming flow).
