A small velocity probe is to be inserted through a pipe wall. If we measure from the outside of the 6-inch schedule 80 pipe, how far (in mm) should the probe be inserted to sense the average velocity if the flow in the pipe is laminar?
Hint: The probe should reach the point where the local velocity (U) is equal to the average velocity.
Answer:
Check
For the flow of 12.9 L/min of water at 75 degrees C in a 1/2-inch type K copper tube, compute the expected maximum velocity of flow in m/s.
Hint: The maximum velocity occurs at the center of the pipe.
