Fluids are everywhere. They flow through rivers and oceans, circulate through our bodies, move through pipes and engines, and even shape the weather around us. Understanding how liquids and gases behave is one of the most important areas of physics, helping scientists and engineers design everything from submarines and airplanes to water systems and medical devices.
This course begins by introducing the fundamental properties of fluids and the concept of density. Students will explore how density is measured, how it influences the behaviour of materials, and why some objects float while others sink. Through practical examples and investigations, they will discover how density helps explain many everyday phenomena.
Students will then examine pressure in fluids, learning how forces are distributed through liquids and gases. They will investigate how pressure changes with depth, how atmospheric pressure affects our environment, and how hydraulic systems use Pascal's Principle to multiply force. These concepts provide an important foundation for understanding many engineering and technological applications.
The course continues with an exploration of buoyancy and Archimedes' Principle. Students will investigate the upward force exerted by fluids and learn how floating and sinking can be explained through the relationship between density, weight, and displaced fluid. They will examine real-world applications involving ships, submarines, hot-air balloons, and aquatic organisms.
Next, students will study fluid flow and Bernoulli's Principle. They will explore how fluids move through pipes and channels, how flow speed and pressure are related, and how these ideas help explain aerodynamic lift and other important engineering principles. Students will discover how fluid flow influences transportation, aviation, and modern technology.
Throughout the course, students will connect fluid mechanics concepts to real-world systems including water distribution networks, weather patterns, ocean currents, biological systems, and engineering design. By combining scientific theory with practical applications, students will develop a deeper understanding of how fluids influence the world around us and how fluid mechanics contributes to solving modern challenges.
