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

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

the answer is b
