Calculator. This calculator computes the Reynolds Number given the flow characteristics asked for below. It outputs the flow type you can expect ( laminar, transitional, or turbulent) based on the Reynolds Number result. Think of the Characteristic Distance as the distance from the leading edge (where the fluid first makes contact) for flow over a. The Reynolds Number calculator will then apply the relevant equation and produce the Reynolds Number (Re) as result. What is the Reynolds Number? The Reynolds number (Re) is a dimensionless quantity for dynamic similarity and is calculated as the ratio of inertial forces to viscous forces of a flow of liquid. Knowing Re one can anticipate the transition from laminar to turbulent flow which is the main utility of a Reynolds Number calculator Reynolds number calculation. The Reynolds number is a dimensionless value that measures the ratio of inertial forces to viscous forces and descibes the degree of laminar or turbulent flow. Systems that operate at the same Reynolds number will have the same flow characteristics even if the fluid, speed and characteristic lengths vary The Reynolds number calculator can either be used in manual mode or alternatively used in with the standard atmosphere calculator. The Reynolds number is an important dimensionless ratio used to predict whether a flow is laminar or turbulent and is defined as the ratio of inertial to viscous forces in a fluid The **Reynolds** **Number** **Calculator** can be used to help predict flow patterns in any kind of flow situation, from pipes and tubes to completely open channels Types of flows There are two types of flows, namely the laminar and the turbulent, while there also is an identifiable transition phase between these two that holds its own significance for practical reasons

Reynolds Number is used to determine flow patterns of a fluid flow, in fluid mechanics. This is a dimensionless quantity. By, definition it is the ratio of the inertial forces to the viscous forces.
