The diffuser in a jet engine is designed to decrease the kinetic energy of the air entering the engine compressor without any work or heat interactions. calculate the velocity at the exit of a diffuser when air at 100 kpa and 30°c enters it with a velocity of 350 m/s and the exit state is 200 kpa and 90°c. (page 216).

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

On a average work day more than work place firs are reorted
