9. FRICTION LOSS ALONG A PIPE

rates show that the critical value of Re for transition to turbulent flow depends on the degree of care taken to eliminate disturbances in the supply and along the pipe. On the other hand, experiments with decreasing flow rates show that transition to laminar flow takes place at a value of Re which is much less sensitive to initial disturbance.
