An engine has an inlet stagnation condition of 300 bar and 4000 kelvin. Methane and liquid oxygen make up the products of combustion and have a specific heat ratio k = 1.14 and a gas constant R = 383 J/kg-k. The nozzle has an exit to throat area ratio of Ae / Ath = 34.34 and has an exit diameter of 1.3 meters. Calculate the following: (d) For launch at sea level Pb = 101.325 kilopascals, is the nozzle over, under, or perfectly expanded? (e) Is the nozzle flow choked? (f) Exit temperature
