Question

Consider the flow of water between two parallel plates in
which one plate is fixed as shown. The distance between the
plates is h, and the speed of the moving plate is V. A person
wishes to calculate the pressure difference between the plates
and applies the Bernoulli equation between points 1 and 2,
and concludes that
Is this correct? Provide the reason for your answer.
Cyclonic Storms
4.102 During the fall of 2005, Hurricane Wilma passed through
the Gulf of Mexico. When the storm was classified as a category
5 hurricane, the pressure at the center of the hurricane was
measured at 902 mbars. The highest wind velocity was 175
mph. Assuming the pressure far from the center of the hurricane
was 1 bar and the air density was 1.2 kg m3, estimate the pressure
at the center of the hurricane. Comment on the difference in
your prediction and the measured value and provide some rationale
for the discrepancy.
4.103 On June 24, 2003, a violent tornado occurred near
Manchester, ND. A pressure drop of 100 mbar was recorded in
the tornado. Assume an air density of 1.2 kg m3 and estimate
the maximum velocity.

Explanation / Answer

Bernoulli equation cannot be used for flow between the plates because the equation is valid only when both the points are on same streamline. (Posting Multiple questions in one question is against Chegg's fair usage policy. Thanks.)
