Turbulent flow occurs when the Reynolds number is above ______?

ہنگامہ خیز بہاؤ اس وقت ہوتا ہے جب رینالڈس نمبر ______ سے اوپر ہو؟
Explanation
  • Reynolds number (Re) determines the type of flow:
    • Re < 2000 → Laminar flow
    • 2000 < Re < 4000 → Transitional flow
    • Re > 4000 - 5000 → Turbulent flow
  • For most practical cases, turbulence begins around Re = 5000.
