Liquid n-octane gas (c8h18) is burned with 80% excess air in a constant pres- sure burner. assume complete combustion. the air and fuel enter this burner steadily at 25°c, 101.325kpa and the products of combustion leave at 317°c. a. calculate the heat transfer in kj/kgful during this combustion

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
