Laminar flow Occurs at low Reynolds numbers, where viscous forces dominate. The fluid flows in smooth layers (laminae). 2. Transitional flow Occurs at intermediate Reynolds numbers, where the flow is unstable and can fluctuate between laminar and turbulent. 3. Turbulent flow Occurs at high Reynolds numbers, where inertial forces dominate. The flow is chaotic with eddies and mixing.For flow in a pipe, the generally accepted ranges are: - Laminar flow $Re Transitional flow $2000 Turbulent flow $Re > 4000$The question asks for the range of Reynolds number for the transition from laminar to turbulent flow. This is the transitional flow regime. Therefore, the generally accepted range for transition is $2000 207. If the gravity of a fluid is made zero then what will not be there?
