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.)
The total entropy change for this process is ______kJ/kg·K.
