Unit-3: First Law of Thermodynamics

Example: 

Diffuser-Nozzle’s Outlet Conditions

Air at 20 kPa and  -35^oC enters a diffuser-nozzle section at 280 m/s. The air goes through a quasi-static adiabatic process until its velocity is reduced to 30 m/s. Calculate the final temperature and pressure (C_P = 1.005 kJ/kg.^oC.)
