Question

Determine total pressure if static pressure is 1600psf and Mach number is 1.8. Consider flow of air.

(a) 9193.2 psf

(b) 1000 psf

(c) 3450 psf

(d) 7892 psf

I have been asked this question in an online quiz.

I'd like to ask this question from Flight Mechanics topic in division Performance and Flight Mechanics of Aircraft Design

Answer 1

The correct choice is (a) 9193.2 psf

To elaborate: Total pressure = static pressure*[1+0.2*Mach number*Mach number]^3.5

= 1600[1+0.2*1.8*1.8]^3.5

= 1600*1.648^3.5 = 9193.2 psf.
