If the flow is laminar, then the Reynolds number is

  2. Between 2000 to 2800

  3. Greater than 2000

  4. Less than 2000

D Correct answer
Explanation

Reynolds number (Re) predicts flow patterns in fluid dynamics. For laminar flow (smooth, orderly fluid motion), Re is typically less than 2000. Between 2000-4000 is transitional, and above 4000 is turbulent. Note that option B says 'Between 2000 to 2800' which incorrectly describes the transitional zone, making option D the clear correct answer.
