Chapter 10: Flow in Conduits - Component or Minor Losses

These flashcards cover key vocabulary and concepts regarding fluid flow in conduits, focusing on minor losses and the associated coefficients and calculations used in engineering.

Coefficient, K

A numerical value determined experimentally that indicates the energy loss factor in fluid flow due to components like fittings in a piping system.

Minor Losses

Energy losses in fluid systems due to fittings, bends, and other transitions that affect flow.

Head Loss Equation

The total head loss in a fluid system is typically calculated as: h_1 = rac{K V^2}{2g}.

Flow Swirl

A disturbance in the flow pattern, usually observed in pipe bends, that can cause variations in pressure and shear stress on pipe walls.

Loss Coefficient

A factor used to quantify the head loss for specific fittings and transitions, listed in fluid mechanics handbooks.

Combined Head Loss

Total head loss in a system calculated by summing the losses due to both pipe and fittings, expressed as: $ext{Total Head Loss} = ext{Pipe Head Loss} + ext{Component Head Loss}$.

Laminar Flow

A type of fluid flow where the fluid moves in parallel layers with minimal mixing, typically characterized by a low Reynolds number.

Turbulent Flow

A type of fluid flow characterized by chaotic property changes, including rapid variation of pressure and flow velocity, usually occurring at high Reynolds numbers.

Friction Factor, f

A coefficient used to represent the resistance to flow in a pipe and is dependent on the flow regime (laminar or turbulent), typically derived from empirical correlations.

Non-Circular Ducts

Ducts or conduits with geometries other than circular, requiring modified formulas for flow calculations, where $D_1 = 4R_h$.
