Fully developed flow is characterized by a constant velocity profile along the pipe’s cross-section and no boundary layer formation. This occurs when the flow has traveled a sufficient distance for the velocity distribution to become independent of the entrance conditions. In fully developed flow, the velocity profile exhibits a parabolic shape in laminar flow and…

The absorbent pad in lateral flow diagnostics provides wicking action, a key factor influencing the efficiency and accuracy of these strips. Its properties, such as capillary action, absorption capacity, porosity, and flow rate, directly impact the fluid flow rate through the membrane, ensuring optimal test performance and result interpretation. Manufacturers like Ahlstrom-Munksjö, MilliporeSigma, and Pall…

Opposite of Flow: Friction creates resistance, Turbulence induces setbacks, Blockage halts progress, Stagnation stalls momentum, and Resistance actively opposes advancements. Friction: The Roadblock to Your Progress Friction, like the annoying screech of your brakes on a wet road, can grind your progress to a halt. It’s the pesky resistance that makes it feel like you’re…

Turbulent channel flow near the wall exhibits distinct velocity profiles due to the interaction between fluid viscosity and wall shear stress. The viscous sublayer adheres to the no-slip condition, forming a thin region where laminar flow dominates. Moving away from the wall, the buffer layer experiences a transition to turbulent flow. The logarithmic layer follows…

The orifice flow equation is a mathematical expression that determines the volumetric or mass flow rate of a fluid passing through a restriction (orifice) in a pipe. It is derived based on principles of fluid dynamics, including Bernoulli’s equation, energy conservation, and mass conservation. The equation incorporates factors such as the orifice geometry, fluid properties,…

Transverse flow effect is a complex phenomenon in fluid dynamics where fluid flow perpendicular to the main flow direction influences heat and mass transfer rates. It arises in multiphase flows, where different phases (e.g., liquid and gas) interact, leading to pressure drops and altered flow patterns. This effect finds applications in power generation and aerospace,…

The appendiceal orifice is the opening of the appendix vermiformis into the cecum. It is located in the posterior wall of the cecum, approximately 2-3 cm below the ileocecal valve. The orifice is surrounded by a sphincter muscle, which helps to regulate the flow of contents into and out of the appendix. The appendiceal orifice…

Plane Poiseuille flow, governed by the Hagen-Poiseuille equation, describes the laminar flow of a viscous fluid in a rectangular microchannel. This flow is characterized by a parabolic velocity profile with a maximum at the channel center. The flow rate is influenced by factors such as viscosity, pressure gradient, and channel dimensions. Plane Poiseuille flow finds…

Compressible Fluid Flow Compressible fluid flow investigates the behavior of fluids at speeds comparable to or exceeding the speed of sound. Unlike incompressible flow, where density remains constant, compressibility effects become significant, leading to shock waves, changes in flow regimes, and complex interactions with boundary layers. By understanding conservation equations, thermodynamics, and flow regimes, engineers…

The coefficient of discharge of an orifice meter expresses the ratio of actual flow rate through an orifice to the ideal flow rate calculated using orifice dimensions and fluid properties. It accounts for flow contraction, pressure recovery, and viscosity effects. The discharge coefficient depends on orifice geometry, pipe diameter, fluid properties, and flow conditions. Orifice…
