Key Terms & Definitions

Important concepts to remember

Fluid Statics

Fluid statics is the study of fluids at rest and the forces exerted by them. It includes concepts like pressure distribution, buoyancy, and forces on submerged bodies.

Related Terms:Hydrostatics

Fluid Dynamics

Fluid dynamics is the study of fluids in motion and the forces that cause fluid movement. It covers flow behavior, velocity, and the principles governing fluid flow.

Related Terms:Hydrodynamics

Reynolds Number

Reynolds number is a dimensionless value used to predict flow patterns, indicating whether the flow will be laminar or turbulent based on fluid velocity, density, and viscosity.

Related Terms:Flow Regimes

Boundary Layer

The boundary layer is the thin layer of fluid near a surface where the fluid’s velocity changes from zero at the surface to the free-stream velocity.

Related Terms:Flow Separation

Continuity Equation

The continuity equation is a principle stating that the mass flow rate of a fluid remains constant in a system, regardless of cross-sectional area changes.

Related Terms:Conservation of Mass

Darcy-Weisbach Equation

The Darcy-Weisbach equation calculates the head loss due to friction in pipe flow, based on factors like pipe length, diameter, and flow velocity.

Related Terms:Frictional Loss

Bernoulli's Equation

Bernoulli's equation describes the relationship between pressure, velocity, and elevation in a fluid flow, based on the conservation of mechanical energy.

Related Terms:Energy Conservation

Turbulent Flow

Turbulent flow is chaotic and irregular flow characterized by eddies and swirls, occurring at higher velocities and Reynolds numbers.

Related Terms:Eddy Currents

Laminar Flow

Laminar flow is smooth and orderly, where fluid flows in parallel layers without disruption, typically occurring at lower velocities.

Related Terms:Streamlined Flow

Hydrodynamics

Hydrodynamics is the branch of fluid mechanics concerned with the study of fluids in motion, particularly with forces and energy transfer.

Related Terms:Fluid Mechanics

Viscosity

Viscosity is a measure of a fluid’s internal resistance to flow, affecting how easily the fluid moves through pipes or other systems.

Related Terms:Fluid Resistance

Pressure

Pressure is the force exerted per unit area by a fluid. It plays a crucial role in fluid statics and dynamics.

Related Terms:Force Per Unit Area

Flow Rate

Flow rate refers to the volume of fluid passing through a cross-sectional area per unit of time, typically measured in cubic meters per second (m³/s).

Related Terms:Discharge

Flow Separation

Flow separation occurs when the fluid detaches from the surface of an object, creating turbulence and an increase in drag.

Related Terms:Boundary Layer

Hydraulic Lift

A hydraulic lift is a system that uses fluid pressure to lift heavy objects, based on Pascal’s Principle.

Related Terms:Pascal’s Principle
