Total Energy At Nozzle Exit For a Piston Engine Calculator

piston engine is commonly found in internal combustion engines like those in cars or small aircraft. The total energy at the exit of a piston engine can be considered in terms of the kinetic energy of the exhaust gases as they leave the exhaust manifold. While it’s not as formally defined as in jet or rocket engines, you can express the total energy per unit mass as the kinetic energy:

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

where,

• E is the Total Energy, i.e sum of kinetic and potential energy
• $h$ is the static enthalpy at the nozzle exit,
• $V$ is the velocity of the exhaust gases relative to the reference frame of the exhaust gases
