The Reynolds Number and Flow Regime Change

The Reynolds Number and Flow Regime Change

Introduction      Flows are normal occurrences that occur and are encountered in day-to-day activities. These flows can be natural or not. But whichever form it is, all flows can basically be classified into the following:a) Flow through open channels (such as falling film) b) Flow through circular ducts; or c) Convective transport of heat In any case it may follow, it is essential in Chemical Engineering, Mechanical Engineering, and other fields to work with the understanding of the regime of flow at an instant…

Determination of Viscosities of Different Fluids

Determination of Viscosities of Different Fluids

Introduction Viscosity refers to the resistance to flow of fluids. It can be defined as the speed of the flow, which depends on the thickness or thinness of the fluid. Viscosity can thus be described as the friction between the molecules in the fluid, which like friction between solid objects, determines the energy required to make a fluid flow. Viscosity in fluid becomes apparent when a layer of fluid is made to move in relation to another layer. It is…

Study of Laminar, Turbulent and Transition Flows

Study of Laminar, Turbulent and Transition Flows

Introduction      Generally, in fluid mechanics, fluid flow are classified into the following: Rotational and Irrotational Flows Steady and Unsteady Flows Compressible and Incompressible Flows One, Two, and Three Dimensional Flows Uniform and Non-Uniform Flows Laminar and Turbulent Flow In this section, laminar and turbulent flows will be discussed.      Laminar flow is a type of flow in which the paths followed by individual particles do not cross one another. This flow is also called viscous flow. Laminar flow gеnеrаllу hарреnѕ whеn…

Safety Guidelines in the Laboratory

Safety Guidelines in the Laboratory

Safety goggles, protective wears, gloves, shoes, helmet, and other Personal Protective Equipments (PPEs) should be used when necessary especially when working with hazardous chemicals Only materials needed for the day’s laboratory exercise should be placed on bench work Always familiarize yourself in advance with an experiment before going to the lab No eating, drinking or any other mouth activity while in the lab Personal materials like bags, books, phones should be kept away from work bench to avoid damage or…
