Which is better Husqvarna or Stihl? I'm trying to settle a debate between a friend and me.
I'm a Husqvarna kinda guy and he's a Stihl kinda guy.
For in general like trimmers, chainsaws, blowers, etc.

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.

Fluids at rest possess no flow energy. a)- true b)- false

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i.e., a violation of one statement leads to the violatio the other statement)
