The stream function (ψ) is a dimensionless quantity in fluid dynamics. It is used to describe the flow pattern of an incompressible and irrotational fluid in two dimensions. The stream function (ψ) is a concept used in fluid dynamics to describe the flow of an incompressible and irrotational fluid in two dimensions. It’s a mathematical […]

Volume flow rate per unit length (Λ) is a measure of the amount of fluid that passes through a specific cross-sectional area of a pipe or conduit per unit length of that pipe. It is a parameter used to characterize and compare fluid flow in different pipes or channels while accounting for their varying lengths.

The term “Volume flow rate per unit length” refers to the amount of fluid that flows through a given cross-sectional area in a pipe or conduit per unit length of that pipe. It is often denoted by the symbol Λ (capital lambda). Volume flow rate per unit length (Λ) is a measure of the amount

Rate of volume flow, which is the amount of fluid passing through a specific point in a system per unit of time. It represents the quantity of fluid moving through a specific point in a system. It describes how much volume of fluid is transported through a particular cross-sectional area over a given time interval. 

Heat transfer is the process of energy exchange between two substances or systems due to a temperature difference. It occurs when there is a difference in thermal energy between two objects or regions, and the energy flows from the higher-temperature region to the lower-temperature region.  qw​: This is the heat transfer rate per unit area

The Prandtl-Glauert parameter, often denoted as β, is a dimensionless quantity used in aerodynamics to correct for compressibility effects in fluid flow, particularly when the flow approaches or exceeds the speed of sound. It is used to transform equations and aerodynamic coefficients that are valid for incompressible flow to account for the changes in flow

Acceleration of an object refers to the rate of change of its velocity with respect to time. It is a vector quantity, meaning it has both magnitude and direction. When an object accelerates, its speed (magnitude of velocity) and/or direction of motion can change.  Buoyancy Force (B) in N  Weight (W) in N  Mass (m)

In aerodynamics, the term “force at sea level” typically refers to the aerodynamic forces experienced by an aircraft or object flying at or near sea level, where atmospheric conditions are relatively standard and the air density is considered constant. The primary aerodynamic forces are lift, drag, thrust, and weight.  Force at sea level in N 

The total drag of a cone refers to the sum of all the aerodynamic forces that act to resist its motion through a fluid, usually air. Total drag encompasses both pressure drag (form drag) and skin friction drag, which are the two main components of aerodynamic drag.  Total Drag (D)  Pressure at a point, p

The skin friction coefficient (cf) is a dimensionless quantity used in aerodynamics to characterize the frictional drag that a fluid, such as air, exerts on the surface of an object as it moves through the fluid. It quantifies the drag caused by the shear stress between the fluid and the object’s surface. For the upper
