A simple wedge with a total included angle of (28^{circ}) is used to measure the Mach number

Question:

A simple wedge with a total included angle of \(28^{\circ}\) is used to measure the Mach number of supersonic flows. When inserted into a wind tunnel and aligned with the flow, oblique shocks are observed at \(50^{\circ}\) angles to the free stream (similar to Figure 7.10).

(a) What is the Mach number in the wind tunnel?

(b) Through what range of Mach numbers could this wedge be useful?
