If the pressure reading of your Pitot tube is 17.0 mm Hg at a speed of 150 km/h, what will it be at 700 km/h at the same altitude?
2. Relevant equations
The only eq I could think if is p = p2+ 1/2 density (v2^2 – v1^2)
But I don’t know the density
3. The attempt at a solution
So I pretty much get stuck in the beginning, any help will be nice
