all of the O2 is removed from the room by some method, what would be the pressure (atm) in the room in the new case assuming ideal gas behavior? (Show your steps.) 2. A stream of air at 90F and 2.00atm is fed to a process at a rate of 20ft3/min. The air stream leaves the process at 650F and 8ft3/min. Calculate the pressure of the air stream leaving the process. 3. A fluid with =0.01g/(cms) is between two plates. The bottom plate is stationary (u=0) and the top plate is moving at constant velocity. The shear stress () on the lower plate surface (at y=0 ) is 0.01Pa. Determine the velocity profile (variation of velocity with vertical distance y from the lower plate). (Show your steps. Pay attention to the consistency of units.)
