The vortex shedding frequency behind a landing gear model is found to be 50 Hz
when tested in a wind tunnel operating at 5 m/s. If the actual landing gear size is
10 times that of the model, and it is designed to operate at 50 m/s, then the
expected vortex shedding frequency behind it is ________ Hz (rounded off to the
nearest integer).
