- The Importance of Balancing: A Deep Dive into Static and Dynamic Balancing in Mechanical SystemsIn mechanical systems, there are two common types of balancing: static and dynamic balancing. Static balancing refers to the even distribution of mass in a stationary object, while dynamic balancing involves balancing rotating components to eliminate any vibrational forces. Understanding the importance of balancing and the techniques involved is crucial for mechanical engineers and anyoneContinue reading “The Importance of Balancing: A Deep Dive into Static and Dynamic Balancing in Mechanical Systems”
- What is Vapour Pressure?The pressure that the liquid’s vapor creates on its surface is known as vapour pressure. At a specific temperature, this pressure forms in a closed container in a thermodynamic equilibrium state. The equilibrium vapor pressure indicates the rate at which liquid evaporates. The temperature increases with vapour pressure. The point at which the pressure fromContinue reading “What is Vapour Pressure?”
- What is Capillarity?Capillarity, or capillary action, is a phenomena in which a liquid will spontaneously rise or fall in a small cross-sectional area tube-like passageway. Surface tension, which is brought on by the cohesion of liquid molecules, and adhesive forces between the liquid and the container wall combine to create capillarity.
- What is heat and mass transfer?Heat transfer- Heat transfer is the science which is used to predict heat transfer which may take place between the body as a temperature difference. DIFFERENCE BETWEEN THERMODYNAMICS AND HEAT TRANSFER NOTE- 1) Whenever a temperature difference exists between two medium or in a medium, heat transfer occurs. 2) If there is concentration difference betweenContinue reading “What is heat and mass transfer?”
- What is Computational fluid dynamics?The study of fluid flow using numerical techniques and algorithms is the focus of the engineering and physics field known as computational fluid dynamics (CFD). It involves simulating the behavior of fluids, including liquids, gases, and multiphase flows, using mathematical models and computer algorithms. Numerous phenomena, such as fluid flow in pipes, heat transfer, combustion,Continue reading “What is Computational fluid dynamics?”
- Properties of fluid (part 3)Viscosity- Resistance to flow of fluid is called viscosity. Reason for viscosity- 1) Cohesive force. 2) Intermolecular momentum transfer. If we plot a graph between perpendicular distance to solid boundary and velocity at that distance, this curve is called velocity profile (or) velocity distribution. NEWTON’S LAW OF VISCOSITY- Newton’s law of viscosity states that shearContinue reading “Properties of fluid (part 3)”
- Properties of fluid (part 2)1) Surface Tension- Free surface of a fluid behaves like a stretched membrane and tries to minimise its area upto maximum possible extent. This property is known as surface tension. Note: 1)Free surface is a surface with constant normal stress and zero shear stress. 2) Normal stress is always equal to the pressure and zeroContinue reading “Properties of fluid (part 2)”
- Property of fluid (Part 1)1) Density or Mass density (ρ) – mass per unit volume is called density. ρ= mass/volume If density increases, so mass increases , so structure is compact or dense medium. If density decreases mass decreases. SI unit of density is kg/m³ Note: Density of water is maximum at 4°C. Density of water at 4°C isContinue reading “Property of fluid (Part 1)”
- What is Macroscopic Approach to Fluid?NOTE: If there are no voids between the molecules, it is called continuous distribution of mass. Knudsen Number (Ku) Knudsen number= mean free path/ characteristic length The distance between two consecutive collision of molecule is called mean free path. The length in which we are analysing the fluid is called Characteristic length. Case 1) IfContinue reading “What is Macroscopic Approach to Fluid?”
- What is Fluid mechanics easy definition?FLUID- Any substance which can flow and is unable to resist shear force or a substance which continuously deform under shear force and it can also flow. Example- Liquid, gas etc. NOTE: 1) SUBSTANCE- Anything which have finite mass, occupies space and can be felt. 2) FLOW- Relative change of position of particle with respectContinue reading “What is Fluid mechanics easy definition?”
