Consider a fluid flowing in a pipe. The density of water ((rho)) is approximately 1000 kg/m¬≥, the velocity (u) is 2 m/s, the characteristic length (L) could be considered as the diameter of the pipe which is 0.1 m, and the viscosity ((mu)) of water is about 0.001 Pa¬...
At low values of the rotational Reynolds number, the flow will be laminar. As the rotational Reynolds number rises, the flow regime will become transitional and then turbulent. The approximate limit for laminar flow is for a rotational Reynolds number somewhere between 40 and 60. Sign in to ...
The critical Reynolds number for dispersed bubbly two-phase flows, gas in liquid, was experimentally investigated. In this experiment, the gas was air and the liquid was water. Water flowed upward through a vertical, translucent pipe, and air was introduced into the...
High-resolution particle image velocimetry (PIV) was used to study the flow characteristics in the near-field of a turbulent square water jet issuing from a smooth contraction nozzle. Mean velocity and turbulence statistics are investigated over a range of jet Reynolds number ReD (based on jet ex...

Reynold's Number - a definition The flow is laminar when Re < 2300 transient when 2300 < Re < 4000 turbulent when 4000 < Re Reynolds Number for one liter of water at approximately 20oC (68oF) flowing through pipes of different dimensions: Water Flow in Tubes - Reynolds Number Pipe Size...
Reynolds number dependence of chaotic mixing of fluids in the partitioned-pipe mixer (PPM) is studied by using numerically obtained velocity fields. We found that transport barriers once expand as the Reynolds number, R_e, is increased. Although they tend to disappear with increase in R_e, so...
6.Checking Options: If we check the options provided in the question, we find that option B states that the Reynolds number is the ratio of inertial force to viscous force, which is correct. Final Answer: The Reynolds number of a flow is the ratio of inertial force to viscous force. ...
The principle that the type of fluid motion, that is, laminar flow or turbulent flow, in geometrically similar flow systems depends only on the Reynolds number; for example, in a pipe, laminar flow exists at Reynolds numbers less than 2000, turbulent flow at numbers above about 3000.McGraw...
