Sampleplane is a plane in a 3d space that passes through the origin (0, 0, 0). normalvector is a vector that is perpendicular to sampleplane. assign inplane with true if testvector lies in sampleplane. note: if testvector is a vector that lies in sampleplane, then the dot product of testvector and normalvector is 0. ex: if testvector is [2, 0, -1] and normalvector is [ 0, 1, 0 ], then inplane is 1 (true). if testvector is [-1, 0.1, 1] and normalvector is [0, 1, 0], then inplane is 0 (false).

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?
