In fluid mechanics, a fluid refers to a substance that can flow and has the ability to deform under applied shear stress. It can include both liquids and gases.Fluids possess properties such as density, viscosity, and compressibility, which play significant roles in their behavi...
In fluid mechanics, µ represents viscosity. Viscosity measures a fluid's resistance to flow. This resistance is caused by shearing stress in the fluid as well as shearing stress between the fluid and its container. Mathematically, viscosity is represented as the ratio of shearing stress to the...
i.e. it has no units. A quantity that has no units is known as a non-dimensional (or dimensionless) quantity. Thus the Reynolds number, Re, is a non-dimensional number.We can go through an example to discover at what velocity the flow in a pipe stops being laminar.If the...

Furthermore, to calculate the temperature we also need to know the rate and the velocity of the fluid at every point . We will not go into the equations involved ,but obviously we have a complicated set of partial differential equations that must be solved by sophisticated procedures, usually...
own internal molecular friction in order for the fluid to flow.In other words, dynamic viscosity is defined as the tangential force per unit area required to move a fluid at a unit velocity in one horizontal plane relative to another, while the molecules of the fluid remain unit distance ...
5Most CFD approaches involve the generation of a grid, or mesh, covering the flow domain. The aim is then to obtain values for the velocity, pressure, temperature, etc. at each grid node (for example, at the centre of each grid volume). The process in CFD is to take the governing,...
If you want to see a modern application of fluid dynamics in action, just take a dip in your local wave pool at an amusement park. There you will see water change form into waves, and then break form again and go back into its regular state (no waves). In neither case is matter cr...
Transient flow is a condition in fluid dynamics in which the velocity and pressure of a fluid flow changes over time due to...
what physics are involved in the 100 meter dash How do we prove that the displacement for a trip is equal to the sum of the dispalcements for each leg of the trip? What is dynamics in engineering mechanics? What is meant by drift velocity?
