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 behav...

What is the driving force for (a) heat transfer, (b) electric current, and (c) fluid flow? What is permeability? What is the unit used for viscosity? What are the factors that affect the flow of fluid in pipes and tubes? What is the difference between flux and flux density?
Where ⍴ is the fluid density,tis time,uthe velocity vector and ∇ the gradient operator. 2. Conservation of Momentum: Newton’s Second Law The momentum equation states that the rate of change of momentum within a fluid volume is equal to the sum of the forces acting on it, including...

In fluid dynamics, incompressible flow refers to a flow in which the density remains constant in any fluid parcel, i.e. any infinitesimal volume of fluid moving in the flow. This type of flow is also referred to as iso…
Linear density is represented mathematically as: µ = mass/length The SI unit of linear density is kg/m. In addition to kg/m, another unit is also used to represent mass per unit length. This is known as the tex, which is the number ofgrams(1 gram = 10-3kg) per 1,000 meters....
