Physics

Air enters a nozzle steadily at 280 kPa and 77°C with a velocityof 70 m/s and exits at 85 kPa and 320 m/s. The heat losses from thenozzle to the surrounding medium at 20°C are estimated to be 3.2kJ/kg.

The table for the ideal-gas properties of air is givenbelow.

Determine the exit temperature. (Round the final answer to onedecimal).

The exit temperature is ______K

Determine the total entropy change for this process. (Round thefinal answer to four decimal places.) (You must provide an answerbefore moving on to the next part.)
