Introduction Fluid statics deals with fluids at rest and a central result is Archimedes’ Principle any object that is completely or partially submerged in a fluid experience an upward force, called the buoyant force, equal to the weight of the fluid that the object displaces. This one principal accounts for why ships float, why a […]
Introduction Liquid cooling systems have a variety of applications in different industries and technologies like automobiles, smartphones and manufacturing. Due to the higher thermal conductivity and specific heat capacity of liquids, they are more efficient compared to gaseous cooling systems. Especially for spaces where the natural airflow cannot be used for effective direct cooling, liquids
Introduction Wind tunnels are essential tools for investigating aerodynamic characteristics and evaluating the performance of airfoils, aircraft, and other engineering structures under controlled airflow conditions. They provide accurate measurements of aerodynamic forces such as lift and drag, which are important for aerodynamic design and validation. Although Computational Fluid Dynamics (CFD) has become a widely used
History: Tesla began experimenting with boundary layer fluid dynamics around 1906. He first publicly showcased a working 200 horsepower model running at 16000 RPM on his 50th birthday July 10, 1906. Tesla filed for his primary turbine patent on October 21, 1909. It was officially granted as U.S. Patent 1061206 on May 6,1913. In a
Cavitation is one of the major fluid mechanics problems which damages ship propellers by reducing their efficiency and ultimately affects their performance. It happens when the local water pressure drops too low, falling below the vapor pressure of water. When this happens, the water boils instantly and creates tiny bubbles filled with water vapor. As
When a fluid flows around a body, forces act between the fluid and the surface due to the viscosity. These intermolecular forces are the cause for the drag, among other things. However, due to the forces acting, the surface of the solid body also tries to bind the fluid to itself. This also leads to
The answer lies in a fascinating principle of fluid mechanics known as the Magnus Effect. It’s an aerodynamic phenomenon that explains how the interaction between a spinning object and the surrounding air creates a sideways force causing the object to follow a curved path. So, what is the Magnus effect? The Magnus effect is an
This project focuses on the computer-aided design (CAD) and virtual assembly of a manually operated arbor press using SOLIDWORKS. The objective was to create a fully functional 3D model that accurately represents the working mechanism of a small bench-mounted arbor press. Individual components were designed separately and then assembled using appropriate mates to ensure proper
If the pressure of a substance is increased during a boiling process, will the temperature also increase or will it remain constant? Why? Ans: If the pressure of a substance increases during a boiling process, the temperature also increases since the boiling (or saturation) temperature of a pure substance depends on pressure and increases with
Classical and the statistical approaches to thermodynamics: Classical thermodynamics is based on experimental observations whereas statistical thermodynamics is based on the average behaviour of large groups of particles. The light-year: In this unit, the word light refers to the speed of light. The light-year unit is then the product of a velocity and time. Hence,
