A resistojet is to be designed to supply a specific impulse of 310s and a total thrust of 10 N. It is to be operated with ammonia in a nozzle with an area ratio of 100:1. The specific-heat ratio during the expansion is 1.3, and the expansion may be assumed (first approximation only) to be adiabatic. Determine the maximum temperature for two cases:
a.No dissociation of the NH3,
b.50% dissociation of the NH3 (into N2 and H2) in the heating chamber, followed by frozen expansion
