Apitot-static probe is used to measure the speed of an aircraft flying at 3000 m. if the differential pressure reading is 3300 n/m2, determine the speed of the aircraft in m/s. the density of air at an altitude of 3000 m is 0.909 kg/m3

the speed of the aircraft is km/h.

   v = 306.76 Km/h

Explanation:

given,

height of the aircraft = 3000 m

differential pressure reading = 3300 N/m²

density of air = 0.909 Kg/m³

speed of aircraft = ?

Assuming the air flowing above air craft is in-compressible, irrotational and steady so, we can use Bernoulli's equation to solve the problem.

using Bernoulli's equation

where ρ is the density of the air at 3000 m

                 v = 85.21 m/s

                 v = 306.76 Km/h

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

the answer is b, have negligible mass
