Question 3
An engineer is trying to measure the local
velouty inside
a bounday layer over a flat plate with a Pitot tube. The Pitot
tube is placed 350 mm from the leading edge, 0.7mm above the vwall.
Air at STP with Loo =20 m/s flows over the flat plate, The Pitot ube
is connected to a wato mano meter which qives a readiig ef 10 mm HzD
The velouity po file
inside the B.L. is givei by:
