Air under standard conditions (ñ=1.23 kg/m3, µ=1.79 x 10 -5) flows through a 4- mm diameter drawn tubing with an average velocity of V = 50 m/s. For such conditions the flow would normally be turbulent. However if precautions are taken to eliminate disturbances to the flow (the entrance to the flow is very smooth, the air is dust free, the tube does not vibrate etc.), it may be possible to maintain laminar flow. What is the pressure drop in...
