Alex is measuring the time-averaged velocity components in a pump using a laser Doppler
Chapter 9, Problem 9-18E(choose chapter or problem)
Alex is measuring the time-averaged velocity components in a pump using a laser Doppler velocimeter (LDV). Since the laser beams are aligned with the radial and tangential directions of the pump, he measures the ur and uu com ponents of velocity. At r 5 5.20 in and u 5 30.0, ur 5 2.06 ft/s and uu 5 4.66 ft/s. Unfortunately, the data analysis program requires input in Cartesian coordinates (x, y) in feet and (u, v) in ft/s. Help Alex transform his data into Cartesian coordinates. Specifically, calculate x, y, u, and v at the given data point.
