Make an exercise problems and model answer of structural integrity evaluation. include following key words. a)-failure assessment diagram b)-fatigue crack growth c)- remained life

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Air (c-1.006 kj/kg. k, r-0.287 kj/kg. k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
