This question is about vapor nozzle
Due to a failure, ammonia in a large container overheats to 1400 kPa, 573 K. At this state, a small crack opens in the container that acts as a nozzle. The outside environment is at 100 kPa, 298 K, and the mass flow rate of ammonia is 10 g/s . Assume negligible nozzle inlet velocity and adiabatic reversible flow. Determine the exit velocity, and the exit cross section.
