1. For laminar flow in a round pipe of diameter D, at what distance from the centerline is the actual velocity equal to the average velocity?

2. Water at 20 degrees C flows through a horizontal 1-mm-diameter tubeto which are attached two pressure taps a distance 1 m apart.(a) What is the maximum pressure drop allowed if the flow is to be laminar? (b) Assume the manufacturing tolerance on the tube diameter is D =1.0 ± 0.1 mm. Given this uncertainty in the tube diameter, what is the maximum pressure drop allowed if it must be assured that the flow is laminar?
