Using ruler and protractor to draw two vectors on the paper, one vector (a) has 10ft magnitude and 30° angle with the x-axis, and the other vector (b) has 30t magnitude and 120° angle with the x-ax is, note. the vector's magnitude (length) can be scaked

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer,e = 5 × 105?
