Problem 4: A thermal rocket has a chamber pressure of 61.5atm and a nozzle with an area ratio of 3.5336. Its vacuum thrust is 3.04×105N larger than the seal-level value. (a) Calculate the sea-level thrust of the rocket using Q1D Isentropic theory. Assume the gas through the rocket has the same thermodynamic properties as air. (5 pts)
