Under standard conditions, ar nows with an average velocity of v = 50 m/s through a 4.0-mm- diameter drawn tubing. in these conditions, the flow is categorically turbulent. however, under certain precautions (.e., the entrance to the tube is very smooth, the air is dust free, and the tube does not vibrate), it is possibly to maintain laminar flow in order to avoid disturbances. calculate the pressure drop (ap) in a 0.1-m length section of the tube if the flow is: 1) laminar [15 marks] ii) turbulent [15 marks] par = 1.23 kg/m2 har 1.79 x 10n-s/m2
