Equivalent airspeed (EAS) refers to the airspeed at sea level in the International Standard Atmosphere (ISA) that would result in the same aerodynamic forces as the true airspeed (TAS) at the current altitude, adjusted for variations in air density. The formula to calculate equivalent airspeed is: Where: EAS is the equivalent airspeed (in m/s), TAS […]

The continuity equation is based on the principle of conservation of mass and states that the mass flow rate is constant in an incompressible fluid flowing through a pipe or a duct. Mathematically, it is expressed as: Where: ρ is the density of the fluid. A is the cross-sectional area of the pipe or duct.
