Ammonia gas flows under pressure through a pipeline, and the flow is throttled by a valve. The pressure and temperature before the valve are 16.9 bar(abs) and 52.2 C, respectively. The valve is controlled such that the pressure after the valve is 5.64 bar(abs). Utilise an equation of state that is based on the principle of corresponding states, together with applicable thermodynamic procedures and calculations, to determine if the temperature of the ammonia after the valve will be below or above 29 C. Do the evaluation within a temperature range of 2 C, and assume that the ideal gas heat capacity of ammonia is a constant value of 36.1 J/(mol.K).
