Joule-Thomson Effect
Introduction The Joule-Thomson Effect (also known as the Joule-Kelvin Effect) is a thermodynamic process where an ideal gas expands without any work being done on or by the system, resulting in a change of temperature. This effect is extensively used in refrigeration systems and air conditioning units. The Joule-Thomson Coefficient The Joule-Thomson coefficient, , quantifies…

Pascal’s Principle
Introduction Pascal’s Principle, also known as Pascal’s law, describes how changes in pressure at any point in an enclosed fluid are transmitted undiminished to all points in the fluid and to the walls of its container. It’s a fundamental principle in the science of hydraulics and plays a crucial role in understanding fluid mechanics. Statement…

Osmosis
Introduction Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. This process is vital for the maintenance of life processes at the cellular level. Basic Principle of Osmosis The basic…

Pressure
Introduction Pressure is a fundamental concept in physics, engineering, and various scientific disciplines. It is defined as the force applied per unit area. In a more general sense, it can also be considered as the measure of the force that a fluid exerts on its surroundings. Basic Definition The basic definition of pressure is given…
