Question:
An aircraft cruises at \(M=0.65\) at \(10 \mathrm{~km}\) altitude on a standard day. The aircraft speed is deduced from measurement of the difference between the stagnation and static pressures. What is the value of this difference? Compute the air speed from this actual difference assuming
(a) compressibility
(b) incompressibility. Is the discrepancy in air-speed computations significant in this case?
