Question

Water flows near a flat surface and soe measurments of the water velocity, u, parallel to the surface, at different heights y above the surface are obtained.  After an analysis of the data, the lab technician reports that the velocity distribution in the range 0 < y < 0.1 ft is given by the equation ( u = 0.81 + 9.2y + (4.1*10^3*y^3)

With u in ft/s and y in ft. (a) Do you think this equation would be valid in any system of units? Explain. (b) Do you think this equation is correct? Explain.

Explanation / Answer

u=0.81 9.2y (4.1x10^3)y^3

distribution in the range 0
