Important concepts to remember
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.
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.
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.
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.
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.
The Darcy-Weisbach equation calculates the head loss due to friction in pipe flow, based on factors like pipe length, diameter, and flow velocity.
Bernoulli's equation describes the relationship between pressure, velocity, and elevation in a fluid flow, based on the conservation of mechanical energy.
Turbulent flow is chaotic and irregular flow characterized by eddies and swirls, occurring at higher velocities and Reynolds numbers.
Laminar flow is smooth and orderly, where fluid flows in parallel layers without disruption, typically occurring at lower velocities.
Hydrodynamics is the branch of fluid mechanics concerned with the study of fluids in motion, particularly with forces and energy transfer.
Viscosity is a measure of a fluid’s internal resistance to flow, affecting how easily the fluid moves through pipes or other systems.
Pressure is the force exerted per unit area by a fluid. It plays a crucial role in fluid statics and dynamics.
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).
Flow separation occurs when the fluid detaches from the surface of an object, creating turbulence and an increase in drag.
A hydraulic lift is a system that uses fluid pressure to lift heavy objects, based on Pascal’s Principle.
