Problem: If the pressure reading of your pitot tube is 15.00 mm Hg at a speed of 200 km/h, what will it be at 700 km/h at the same altitude?

FREE Expert Solution

From Bernoulli's theorem, the change in pressure is given by:

P=12ρv2

The pressure reading in the pitot tube is the pressure difference.  

If the same fluid is passing through the pitot tube at the same altitude, then the change in pressure is directly proportional to the square of velocity. i.e ΔP ∝ v2
