This can be done w/o too much trouble. Anemometers such as are used in HVAC work are not too expensive. I actually have a very nice fan type with great bearings but I haven't had time to calibrate it, measure the stall speed and stick it in my little brake duct that I don't need anyway...
Heated bead or hotwire types are common these days. They give very local readings, but you can just measure at teh center and near the walls to get an idea of the profile.
You aren't tired of experimenting are you Jack???
