Answer:
C
Explanation:
Pitot tube:
Pitot tube is a device which is used to measure the velocity of flow by measuring pressure difference between the points.
As we know that stagnation pressure is the summation of dynamic and static pressure.
Stagnation pressure = Static pressure + Dynamic pressure
So
Dynamic pressure = Stagnation pressure - Static pressure
We know that dynamic pressure
On the other hand Pitot tube measure the dynamic pressure.
So option C is correct.

<u>Problem 1</u>
The critical t-value, as mentioned previously, would be , making the 95% confidence interval equal to
This interval suggests that we are 95% confident that the true mean levels of lead in soil are between 381.5819 and 398.9181 parts per million (ppm), which satisfies the EPA's regulated maximum of 400 ppm.
