Question:

A gas at T = 450°C and P = 5 bar flows at steady state through an adiabatic and reversible nozzle. The exiting pressure is 1 bar. Find the velocity and temperature of the exiting stream if

A. The gas is steam.

B. The gas is an ideal gas with C_V* = 3R and molecular weight = 75 g/mol. Tin = 450C Pin = 5 bar FIGURE 4-14 Nozzle described in Example 4-6. Tout = ? Pout = 1 bar V = ?
