**Venturi meters : A Venturi meter is used to measure the flow rate through a tube.
Magnus Effect: Spinning ball deviated to its usual path in flight
**Continuity equation is the mathematical way to express mass conservation
**Bernoulli's equation : It relates the Kinetic energy of a fluid at a point, the pressure energy of fluid at that point and the potential energy of that point above a reference level. Or you can say It is just the application of work-energy theorem in the case of fluid flow.
**kinetic energy : It is the energy of fluid molecules associated due to motion of fluid particle
**Pressure energy : It is the energy stored in a fluid due to the force per unit area applied on it.
**potential energy : The energy possessed by a body by virtue of its position relative to others.
**Bernoulli Theorem : The sum of pressure energy, potential energy and kinetic energy per unit mass is constant at all cross-section in the streamline steady flow of an ideal liquid
**Assumptions :
**Flow should be steady flow
**Valid for Incompressible ideal fluid (Non-viscous so no energy loss by friction)
**Irrotational flow (Angular Momentum at any point should be zero)
**Ideal Fluid : A fluid is said to be ideal if it is assumed to be both incompressible and non viscous
**Ideal Plastic fluid : A fluid, in which shear stress is more than the yield value and shear stress is directly proportional to the rate of shear strain, is known as Ideal Plastic fluid
**Real fluid : Fluid that have viscosity is greater than zero
**A compressible fluid : Fluid in which significant density variations that occur during its flow.
**Incompressible flow : Fluid flow in which the fluid's density is constant.
**Newton's viscosity law's : It’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers. The ratio of shear stress to shear rate is a constant
**Newtonian fluid : Fluid that does follow Newton's law of viscosity
Exam : Water, Honey & Organic Solvents,
**Non-Newtonian fluid : Fluid that does not follow Newton's law of viscosity
Examples : Toothpaste, Shampoo, Paint or Blood
**Hydrodynamics is the study of liquids in motion. Hydraulic applications are pipe flow, dam design, (fluidics and fluid control circuitry.
** Study flow: when velocity of fluid flow will not change with respect to time is called steady flow
**Unsteady flow: when velocity of fluid flow will change with respect to time is called steady flow
**•Incompressible Flow. Incompressible flow is type of flow in which density of fluid remains constant
**•Compressible Flow. Compressible flow is flow in which density of fluid changes with respect to distance
**Laminar Flow: the flow of a fluid when each particle of the fluid follows a smooth path, paths which never interfere with one another
** Turbulent Flow: irregular flow that is characterized by tiny whirlpool regions.
