The Blasius Solution to the laminar flow along a flat surface gives u/u? of 0.9916 at an ? of 5.0. Why is this usually given as the boundary layer thickness?
What will be an ideal response?
The value of 0.9916 represents the situation where the boundary velocity is
99.16% of the free stream fluid velocity and this is reasonably close for
measurement purposes

Temperature Scales: At what, if any, temperature are the numerical readings on the Fahrenheit and Celsius scales the same?
A. -30° B. -40° C. -50° D. -60° E. They can never read the same because they are based on different zeroes.
Suppose we synchronize two atomic clocks at a point at 45° south latitude, and then move one clock directly north to the earth’s equator and the other directly south to the south pole, where they remain for some years in climate-controlled enclosures that keep them at the same temperature and humidity. We then reunite the clocks at the origin point and compare them again. Which (if either) has registered a shorter time between the synchronization and comparison events?
A. The clock at the equator B. The clock at the south pole C. Both clocks read the same time
