Determine the lubrication parameters with u=0.03350 pa. s, n =600rpm, 20mm, l=40 the average oil film temperature in oil bath and moving air condition and ambient temperature 30°c, use at least 3 iterations. state whether you should change the oil. what happens if you instead use sae 70 at 80°c with the shaft still rotating at the same n? compare each values of each parameter.

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

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