Total Energy At Nozzle Inlet For a Turbofan Engine Calculator

This formula accounts for both the internal energy associated with the temperature and pressure of the incoming air (static enthalpy) and the energy associated with the motion of the air (kinetic energy).

To use this formula, you would need specific values for the static enthalpy and the velocity of the incoming air. These values are typically provided in the engine specifications or can be calculated based on the ambient conditions and the design of the engine.

The total energy ($E$) at the nozzle Inlet can be expressed as:

where,

• E is the Total Energy, i.e sum of kinetic and potential energy
• $h$ is the Static Enthalpy at nozzle Inlet,
• $V$ is the velocity of the incoming air relative to the reference frame of the engine.
