The static temperature is defined based on the concept of conservation of total energy in a fluid flow. For an adiabatic and reversible process, the static temperature is the temperature a parcel of gas would have if it were brought to rest isentropically (without any heat exchange with the surroundings) and isentropically compressed or expanded to its current state.Â
