Problem

In an open-air experiment, a Pitot tube with its static pressure tapping situated

0.25\,\text{m}

above the stagnation point is connected to a water manometer. The water column shows a height difference of

12\,\text{cm}

. Given

\rho_{\text{water}}=1000\,\text{kg m}^{-3}

\rho_{\text{air}}=1.2\,\text{kg m}^{-3}

and

g=9.8\,\text{m s}^{-2}

, determine the speed of the air stream, accounting for the elevation difference between the two tapping points.
