Atank at howard's engineering building has air in it. if 10lb of air is in this tank at 550 or and at a pressure of 50 lbf/in^2, determine the volume of the air in ft. for the air is to be treated as an ideal gas, the molecules in the tank should not experience the forces between each other. verify that it is an ideal gas.

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?
