Why you determine reynold number in fluid mechanics?
Reynolds number tells you what the flow is doing. A Reynolds number of 0-2000 is laminar flow 2000-4000 is the transition (where both laminar and turbulent flow is possible) 4000+ is fully turbulent flow
What are the application of Reynolds model law?
flow in closed pipes,flow meterflow around immersed bodies like aeroplane,submarine.
What are the factors that affect the air movement?
reynolds number less than 2000 is laminar flow and reynolds number greater than 4000 is a turbulent flow
Reynolds number in terms of inertial force and viscous force?
Reynolds number is the ratio of inertia force to the viscous force. Reynolds number is used to find out the flow whether it is laminar or turbulent.
What are disadvantages and advantages of laminar flow?
Disadvantage: It takes energy to move the fluid. Advantage: It helps boats move since there aren't any waves.
What is Reynolds number?
Reynolds number Re is a dimensionless number that gives a measure of the ratio of internal forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions
What happen if Reynolds number is increased?
flow become turbulent. for ex. if Re <2000 flow is turbulent and if Re >4000 flow is turbulent and if RE is in between these values the flow is in transition region
How can we relates the Reynolds Number with the phenomena of turbulence and laminar?
Turbulent flow occurs above a certain Reynold's number; laminar flow occurs below a certain Reynold's number. The exact value of the Reynold's number required for flow to become turbulent varies, depending on the specific situation.

What is the Graetz number?
The Graetz number is {(Diameter/Length)*Reynolds#*Prandtl#}^(1/3) It is used to characterize the thermal development of pipe flow: if the Graetz number is less than 1000, the thermal profile is fully developed.
