The flow work equation is fundamental in fluid mechanics, particularly in the study of thermodynamics and energy transfer within fluid flow systems. The flow work equation is given by: Where: Wf​ is the flow work, measured in energy per unit mass,  is the pressure exerted by the fluid, typically in Pascals (Pa) or any pressure […]

The momentum equation, in the context of fluid mechanics, relates the net force acting on a fluid system to the rate of change of momentum. It is derived from Newton’s second law of motion, which states that the rate of change of momentum of an object is equal to the net force acting on it.

The Pitot-static tube is a device used to measure fluid flow velocity, particularly in air and gases. It works based on the principles of Bernoulli’s equation and involves two pressure measurements, the stagnation pressure (total pressure) and the static pressure. By comparing these pressures, the velocity of the fluid can be determined. The Pitot-static tube

The compressible boundary layer equations describe the behavior of the thin layer of fluid adjacent to a solid surface in a compressible fluid flow. One of the key parameters characterizing compressible boundary layers is the local Mach number (M), defined as the ratio of the local flow velocity to the local speed of sound, such

The laminar boundary layer equation describes the behavior of a laminar boundary layer, which forms when a fluid flows over a solid surface. In this region, the fluid moves smoothly in parallel layers, with minimal mixing between adjacent layers. The Blasius solution provides an expression for the boundary layer thickness (δ) as a function of

The turbulent boundary layer equation describes the behavior of a turbulent boundary layer, which forms when a fluid flows over a solid surface. In this region, the fluid velocity changes rapidly in the direction perpendicular to the surface due to the interaction between the fluid and the solid boundary. The equation for the turbulent boundary

The equation governing cavitation depends on the specific conditions of the flow and the properties of the fluid. One important parameter used to characterize cavitation is the cavitation number (σ), defined as the ratio of the local pressure drop to the pressure of the fluid vapor, Where: P vapor​ is the vapor pressure of the

A Reversible Process in thermodynamics is a hypothetical process in which a system undergoes a series of changes in such a way that both the system and its surroundings can be returned to their original states without leaving any trace or causing any change in the surroundings. In essence, a reversible process is one that

An Isothermal Process is one that occurs at a constant temperature. During an isothermal process, the system exchanges heat with its surroundings in such a way that the temperature remains constant throughout. However, for an ideal gas undergoing an isothermal process, the relationship between pressure (P), volume (V), and temperature (T) is given by Where:
