Chapter 3, Problem 3.5P
Assume that a Pitot tube is inserted into the test-section flow of the wind tunnel in Problem 3.4. The tunnel test section is completely sealed from the outside ambient pressure. Calculate the pressure measured by the Pitot tube, assuming the static pressure at the tunnel inlet is atmospheric.

Problem 5. The fully-developed velocity profile for laminar flow in a pipe is very different from that for turbulent
flow. For laminar flow, the velocity profile is parabolic (where is centerline velocity):
V=1-(+)²
For turbulent flow, the time averaged velocity profile can be approximated by a power-law profile:
= (1-)
Find the ratio of average velocity to centerline velocity, V/Ve, and the dimensionless radial location, 1* = r/R.
where you would need to place a Pitot tube if it is to measure the average velocity in the pipe for (a) laminar flow
and (b) turbulent flow with n = 6.0 at Rep = 20,000.
NOTE: For the integration of the turbulent profile, let r* = r/R and y* = 1 - *.

water level in the sump is 3 m below the pump cylinder axis.
