💠 Fluid Mechanics
Fluid mechanics: is an important branch of physics that deals with the study of fluids (both liquids and gases) and their behavior in various situations.
👉 here are some key concepts in Fluid Mechanics:
🔻 Pascal's Law: This law states that a change in pressure applied to an enclosed fluid is transmitted equally in all directions.
👉It helps explain how hydraulic systems work, where a small force can be amplified to produce a larger force.
🔻 Archimedes' Principle: This principle states that an object immersed in a fluid experiences an upward buoyant force equal to the weight of the displaced fluid.
👉It helps determine whether an object will sink or float in a fluid.
🔻 Bernoulli's Principle: According to this principle, as the speed of a fluid increases, its pressure decreases.
👉This principle is used to explain the lift generated by airplane wings and the flow of blood in arteries.
🔻 Viscosity: is a measure of a fluid's resistance to flow.
👉It depends on the internal friction between fluid layers.
👉High viscosity fluids have a thick consistency (e.g., honey), while low viscosity fluids flow easily (e.g., water).
🔻Reynolds Number: is a dimensionless quantity used to predict the flow pattern of a fluid (laminar, turbulent, or transitional).
👉It is calculated based on the fluid's velocity, density, viscosity, and characteristic length scale.
🔻 Fluid Pressure:
Pressure is the force applied per unit area.
In fluid mechanics, pressure is calculated using the relationship
P = F/A, where P is pressure,
F is force, and A is the area over which the force is distributed.
🔻 Fluid Flow: refers to the motion of fluids.
👉It can be described as steady or unsteady, laminar or turbulent, and viscous or non-viscous.
👉Understanding the different types of flow is crucial in various engineering applications.
