Question 11: A non-flat plate is placed inside a wind tunnel where the air velocity in the test section is set at 0.5 m/s. Pitot tube is used to measure the difference of static and stagnation pressure, which is converted to find the velocity. The pitot tube is placed above the flat plate and can be adjusted in the direction perpendicular to the flat plate to measure the air velocity parallel to the flow in the boundary layer. Suppose the velocity at the middle of the boundary layer thickness is measured as 0.35 m/s, determine the relation of boundary layer thickness, displacement thickness, and momentum thickness to the distance from the leading edge using approximation method if the velocity profile is (a) linear, and (b) parabolic.

Question
Transcribed Image Text:Question 11: A non-flat plate is placed inside a wind tunnel where the air velocity in the test section is set at 0.5 m/s. Pitot tube is
used to measure the difference of static and stagnation pressure, which is converted to find the velocity. The pitot tube is
placed above the flat plate and can be adjusted in the direction perpendicular to the flat plate to measure the air velocity
parallel to the flow in the boundary layer. Suppose the velocity at the middle of the boundary layer thickness is measured as
0.35 m/s, determine the relation of boundary layer thickness, displacement thickness, and momentum thickness to the
distance from the leading edge using approximation method if the velocity profile is (a) linear, and (b) parabolic.
