Consider external flow dynamic pressure as 2000psf and static pressure as 800psf. find the approximate value of Mach number.

Consider external flow dynamic pressure as 2000psf and static pressure as 800psf. find the approximate value of Mach number. Correct Answer 1.9

Mach number = (dynamic pressure / (0.7*Static pressure))0.5 = (2000 / (0.7*800))0.5 = 3.5710.5 = 1.88 = 1.9.
