What is the stagnation pressure?Group of answer choicesThe sum of the static pressure and the specific kinetic energyThe pressure that would be reached during adiabatic, reversible stagnation of a moving fluidThe pressure that would be reached during an adiabatic deceleration of a moving fluid (reversible or irreversible)All of the above

Through an adiabatic, reversible nozzleGroup of answer choicesThe static enthalpy and static pressure decrease, the stagnation enthalpy remains constant, but the stagnation pressure decreasesThe static enthalpy and static pressure decrease, and the stagnation pressure and stagnation enthalpy remain constantThe static enthalpy and static pressure decrease, and both the stagnation enthalpy and stagnation pressure decrease.All of the above
