Nozzle Exhaust Air Velocity For a Turbofan Engine Calculator

In a turbofan engine, the nozzle exhaust air velocity is the speed at which the exhaust gases exit the engine nozzle. This velocity is a crucial parameter as it directly influences the thrust generated by the engine. The turbofan engine is a type of airbreathing jet engine that is commonly used in aircraft propulsion.

The continuity equation is based on the principle of mass conservation, and Bernoulli’s equation expresses the conservation of energy.

The continuity equation is given by:

A1​⋅V1​=A2​⋅V2​

where:

• A1​ and A2​ are the cross-sectional areas at the nozzle entrance and exit, respectively,
• V1​ and V2​ are the velocities at the nozzle entrance and exit, respectively.

which gives

where,

• A₁ is the Area of Nozzle Inlet in m²
• A₂ is the Area of Nozzle Exhaust in m²
• V₁ is the Inlet air Velocity in m/s
• V₂ is the Exhaust Air Velocity in m/s
