Which process limits optimal multistage rocket efficiency when exhausting through a de Laval nozzle?

💡 Explanation

A rocket nozzle operating between heat reservoirs mimics a Carnot cycle; real nozzles generate entropy due to friction and turbulence, leading to non-isentropic behavior and reducing overall exhaust velocity, because energy is dissipated, therefore efficiency declines, rather than an ideally reversible process.
