Bernoulli's equation along the streamline that begins far upstream of the tube and comes to rest in the mouth of the Pitot tube shows the Pitot tube measures the stagnation pressure in the flow.

Its velocity then increases to 12 m/s. Calculate the average velocity of the bus over the journey. Final velocity = 12 m/s. Initial velocity = 4 m/s. Average velocity = \(\frac{\text{initial ...
