Reynolds Transport Theorem
Key Concept: The Reynolds Transport Theorem provides a way to transfer equationsfor conservation of mass, momentum, and energy from the Lagrangian point of view to the Eulerian point of view using a control surface and…
CONCEPT OF CONTROL VOLUME
A specified large number of fluid and thermal devices have mass flow in and out of a system called as control volume. 1.CONTINUITY EQUATION Concepts The continuity equation is governed…
CAPILLARITY
Capillarity is defined as a phenomenon of rise or fall of a liquid surface in a small tube relative to the adjacent general level of liquid when the tube is…
VISCOSITY
Viscosity is defined as the property of a fluid which offers resistance to the movement of one layer of fluid over adjacent layer of the fluid. When two layers of a…
FLUID PROPERTIES
1 Density or Mass density: Density or mass density of a fluid is defined as the ratio of the mass of a fluid to its volume. Thus mass per unit…
FLUID PROPERTIES AND FLOW CHARACTERISTICS
PRE REQUEST DISCUSSION This page broadly deal with units and dimensions, properties of fluids and applications of control volume of continuity equation, energy equation, and momentum equation. Man’s desire for knowledge…
Flotation, centre of buoyancy
The first dash point under fluid mechanics is flotation, centre of buoyancy. These two concepts are put together because floatation is caused by a force known as buoyancy. For an…
Buoyancy and Floatation: Differences, Problems and Solutions
1. Meaning of Buoyancy: Consider a body immersed in a liquid. Consider an elemental vertical cylinder of the body of height y and sectional area da. Let the intensity of pressure…
Pressure measurement
Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement…
Properties of Fluids
properties of fluids determine how fluids can be used in engineering and technology. They also determine the behaviour of fluids in fluid mechanics. The following are some of the important basic properties of fluids:…
