When an airplane is flying 200 mph at 5000-ft altitude in a standard atmosphere, the air velocity at a certain point on the wing

Sedaia [141]

Answer:

P1 = 0 gage

P2 = 87.9 lb/ft³

Explanation:

Given data

Airplane flying = 200 mph = 293.33 ft/s

altitude height = 5000-ft

air velocity relative to the airplane = 273 mph = 400.4 ft/s

Solution

we know density at height 5000-ft is 2.04 × $10^{-3}$ slug/ft³

so here P1 + $\frac{\rho v1^2}{2}$ = P2 + $\frac{\rho v2^2}{2}$

and here

P1 = 0 gage

because P1 = atmospheric pressure

and so here put here value and we get

P1 + $\frac{\rho v1^2}{2}$ = P2 + $\frac{\rho v2^2}{2}$

0 + $\frac{2.048 \times 10^{-3} \times 293.33^2}{2}$ $= P2 + \frac{2.048 \times 10^{-3} \times 400.4^2}{2}$

solve it we get

P2 = 87.9 lb/ft³
