What is Fluid Mechanics?

Fluid mechanics is the branch of physics that deals with the study of fluids in motion. It involves understanding the behavior of fluids under various forces, such as gravity, pressure, and friction. Fluid mechanics is a fundamental subject that has numerous applications in engineering, physics, and other fields.

Types of Fluids

There are several types of fluids, including:

• Liquids: Liquids are fluids that have a definite volume but take the shape of their container. Examples of liquids include water, oil, and juice.
• Gases: Gases are fluids that have neither a definite shape nor a definite volume. Examples of gases include air, helium, and oxygen.
• Plasmas: Plasmas are ionized gases that contain charged particles. Examples of plasmas include stars, lightning, and neon signs.

Fundamental Principles of Fluid Mechanics

Fluid mechanics is based on several fundamental principles, including:

• Conservation of Mass: The law of conservation of mass states that the mass of a fluid remains constant over time.
• Conservation of Momentum: The law of conservation of momentum states that the momentum of a fluid remains constant over time.
• Energy Equation: The energy equation states that the total energy of a fluid remains constant over time.
