What is the difference between the actual velocity and the ideal velocity in fluid flow?
Ideal Velocity: The velocity a fluid would have in an ideal, frictionless scenario (without viscosity or turbulence). Actual Velocity: The velocity that the fluid actually has, which is influenced by factors like viscosity, turbulence, and boundary effects.

See lessWhat is the difference between open channel flow and pipe flow?
Open Channel Flow: Flow in an open channel (like rivers or canals) where the fluid is not confined to pipes. The free surface of the fluid is exposed to the atmosphere. Pipe Flow: Flow in a closed conduit (such as a pipe), where the fluid is enclosed and there is no free surface.

See lessWhat is the continuity equation?
The continuity equation is based on the principle of conservation of mass. It states that for an incompressible fluid, the mass flow rate is constant along a streamline. Formula is written as:- A1v1=A2v2A_1 v_1 = A_2 v_2 where: A1,A2A_1, A_2 = cross-sectional areas at two points, v1,v2v_1, v_2 = veRead more

where:
NOTE:- if the flow area decreases, the velocity of the fluid must increase, and vice versa.
See lessWhat is the difference between pressure and head in fluid mechanics?
Pressure:- It refers to the force exerted by a fluid per unit area. It is typically measured in Pascals (Pa) and can be static (due to fluid at rest) or dynamic (due to fluid in motion). Head:- It is a measure of the energy per unit weight of fluid, expressed in terms of the height of a fluid columnRead more
Pressure:-

Head:-
It is a measure of the energy per unit weight of fluid, expressed in terms of the height of a fluid column. It is typically measured in meters and is used to express the potential energy (elevation head), kinetic energy (velocity head), or pressure energy (pressure head) of a fluid.
See lessWhat is viscosity?
Viscosity is a measure of a fluid’s resistance to deformation or flow. It can be thought of as "thickness" or "stickiness" of a fluid. High viscosity fluids (like honey) flow slowly, while low viscosity fluids (like water) flow easily.

See lessWhat is Bernoulli's Equation?
Bernoulli's equation is a principle of fluid dynamics that describes the behavior of a moving fluid. It states that in a steady, incompressible flow, the total mechanical energy (pressure energy, kinetic energy, and potential energy) remains constant along a streamline. Mathematically: P+12ρv2+ρgh=cRead more

See lessWhat is the Reynolds number?
The Reynolds number (Re) is a dimensionless quantity that predicts the flow regime (laminar or turbulent). A low Reynolds number indicates laminar flow, while a high Reynolds number indicates turbulent flow.\rho

See lessWhat is the difference between laminar and turbulent flow?
Laminar Flow: A type of flow where fluid moves in smooth layers or paths, with minimal mixing between layers. It occurs at low velocities and when the Reynolds number is below a critical value (typically Re < 2000). Turbulent Flow: A chaotic flow characterized by eddies and swirls, where fluid paRead more

Turbulent Flow:
A chaotic flow characterized by eddies and swirls, where fluid particles move irregularly. It occurs at higher velocities and when the Reynolds number exceeds a critical threshold (typically Re > 4000).

Fluids can be classified based on their properties:- Ideal Fluid: A hypothetical fluid that is incompressible and has no viscosity (resistance to flow).

- Incompressible Fluid: A fluid with constant density, typically used for liquids.
- Compressible Fluid: A fluid whose density changes significantly with pressure, typically gases.
- Newtonian Fluid: A fluid whose viscosity is constant and independent of the shear rate (e.g., water, air).
- Non-Newtonian Fluid: A fluid whose viscosity changes with the shear rate (e.g., blood, ketchup).
See lessWhat is fluid mechanics?
Fluid mechanics is the study of fluids (liquids and gases) and the forces acting on them. It is concerned with how fluids behave when they are at rest (fluid statics) and when they are in motion (fluid dynamics).
