7.22 A flat plate 1.5 m long and 0.3 m wide is towed at 3 m/s in a towing basin containing water at 20 C. The measured drag force is 14 N. Calculate the dimensions of a similar plate that will yield dynamically similar conditions in an airstream at a velocity of 18 m/s, 101.4 kPa, and 15 C. Determine the expected drag force plate in the air stream.
