The study of fluids and their behaviour is the focus of the engineering and physics field known as fluid mechanics. Understanding fluid mechanics is essential for many mechanical engineering applications, including designing pumps, turbines, and hydraulic systems. This article intends to give students seeking a B.Tech in mechanical engineering a thorough introduction of fluid mechanics.

### Importance of Fluid Mechanics

In mechanical engineering, fluid mechanics is crucial. It provides the groundwork for comprehending and analysing how fluids behave in diverse engineering systems. For the purpose of building effective and secure mechanical systems, a strong understanding of fluid mechanics is required, regardless of whether the fluid is the flow of gases via pipelines or the movement of liquids in hydraulic gear.

### Fundamental Concepts in Fluid Mechanics

Basic ideas must be understood in order to understand fluid mechanics. Viscosity, density, pressure, and velocity are some of these ideas. Density is a fluid’s mass per unit volume, whereas viscosity is a fluid’s resistance to flow. Velocity and pressure are terms used to describe the speed and direction of fluid flow, respectively.

### Course Objective:

1. Establish a strong foundation in fluid mechanics’ core ideas and principles.

2. Be familiar with the properties and traits of fluids, such as surface tension, density, and viscosity.

3. Acquire knowledge on how to evaluate and compute pressures, forces, and velocities in a variety of fluid systems.

4. Learn about fluid statics, including how to calculate the hydrostatic forces acting on floating and submerged objects.

5. Learn about fluid dynamics, particularly how Bernoulli’s principle is used and the idea of Reynolds numbers.

6. Develop the ability to monitor and evaluate fluid flow rates using a variety of methods and tools.

7. Recognise the value of fluid mechanics in mechanical engineering and how it applies to different engineering fields.
