Volume flow rate is a measure of the volume of fluid passing through a given cross-sectional area in a fluid system per unit of time. It represents how much fluid flows through the system in a specific time interval.  v̇: This represents the volume flow rate in m³/s r: This represents the radial distance from […]

Mass flow rate is a fundamental concept in fluid mechanics and thermodynamics. It refers to the amount of mass that passes through a given cross-sectional area in a fluid system per unit of time.  ṁ (m-dot) is the mass flow rate (kg/s), 2𝜋 is the constant representing the circumference of a circle, r is the

The volume flow rate (v̇) is the rate at which fluid flows through a specific cross-sectional area and is defined as the volumetric flow per unit time.  v̇ is the volume flow rate (measured in m³/s). ṁ is the mass flow rate (measured in kg/s). ρ is the density of the fluid (measured in kg/m³).

Velocity (V) at a specific point on an aerodynamic body or airfoil refers to the magnitude and direction of the fluid flow’s speed at that particular location on the surface of the body. In fluid dynamics, velocity is a vector quantity, meaning it has both magnitude (speed) and direction. At any given point on an

The pressure at a specific point in a fluid flow depends on various factors, including the fluid’s velocity, density, and the geometry of the flow field. It helps us to determine the pressure distribution and aerodynamic behavior of different shapes and optimize designs for various applications. This equation is commonly used in aerodynamics and fluid

The coefficient of pressure (Cp) is a dimensionless quantity used in fluid dynamics and aerodynamics to describe the pressure distribution around an object, typically an airfoil or an aerodynamic body. It provides a normalized representation of the pressure at different points on the surface of the object with respect to the free-stream or ambient pressure. 

Bernoulli’s equation for total pressure, also known as the Total Energy Equation or the Stagnation Pressure Equation, is a variation of Bernoulli’s equation that accounts for the total pressure along a streamline in an incompressible, inviscid fluid flow. It is used to describe the conservation of total pressure between two points along a streamline, assuming

In a diffuser, the inlet velocity refers to the velocity of the fluid at the entrance or inlet of the diffuser. The diffuser is a device designed to slow down the fluid and increase its pressure by gradually expanding the flow area. When fluid enters a diffuser, it typically has a certain initial velocity (V1)

The velocity flow of an incompressible, inviscid fluid along a streamline is governed by Bernoulli’s equation. This equation describes the conservation of energy along a streamline in a steady flow of an ideal fluid, where no energy is lost due to friction or viscosity.  V is the velocity at a specific point in the flow

The time period of a pendulum’s oscillation refers to the time it takes for the pendulum to complete one full back-and-forth swing, from one extreme point to the other and back again. It is the time duration of a single oscillation.  T is the time period of the pendulum’s oscillation (measured in seconds). π (pi)
