A liquid flowing through a tube has Reynolds number $R_n = 500$. Its flow is:
ALaminar (streamline)
BTurbulent
CTransitional
DCannot be classified
Answer & Solution
Correct answer: A. Laminar (streamline)
$R_n < 1000$: streamline/laminar flow. $1000 < R_n < 2000$: transitional. $R_n > 2000$: turbulent. At 500, well within laminar regime.
