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 wall.
Air at STP with Loo =20 m/s flows over the flat plate, The Pitot tube
is connected to a wate mano meter which qires
a reading ef 10 mm Hz0.
The velouity profile inside the B.L. is givei by:
