A gas flows through an adiabatic nozzle (Figure 6-7) at steady state, entering at P = 5

Question:

A gas flows through an adiabatic nozzle (Figure 6-7) at steady state, entering at P = 5 bar and T = 400°C, and leaving at P = 1 bar. Assuming the nozzle is reversible, what is the temperature of the exiting gas? Assume the gas has a constant heat capacity of CP = 40 J/mol · K and follows the equation of state: V RT P + aTP cm mol bar. K where a = 1.00- P= 5 bar T = 400C P = 1 bar T = ?
