Solved: Carbon dioxide enters an adiabatic nozzle steadily

Step 1 of 4

 gas is accelerated in a nozzle to . The inlet velocity and the exit temperature are to be determined.

Assumptions are

1. This is a steady-flow process since there is no change with time.

2.  is an ideal gas with variable specific heats.

3. Potential energy changes are negligible.

4. The device is adiabatic and thus heat transfer is negligible.

5. There are no work interactions.

The gas constant and molar mass of  are  and  (Table A-1). The enthalpy of  at  is  (Table A-20).
