1. (16 pts) A radio antenna on a car tends to vibrate because of the steady frequency of vortices that are shed in the wake of the antenna. Your boss has asked you to design a test in a water channel which will simulate the vortex shedding from an antenna. The antenna diameter is d = 5 mm and the velocity of interest is V = 30 m/s. Other relevant variables are density P, viscosity , and of course the shedding frequency 0. a. Given that one of the II terms is д what are the other II terms? PVD' b. If the diameter of model antenna used in the water channel is 10 mm, what velocity should be used in the water channel to correctly simulate the car antenna? = c. If a shedding frequency of o = 22 Hz is measured in the water channel, what is the shedding frequency expected for the antenna on the car?
