g What is the resultant phase or phases present in this eutectoid steel after the following heat treatment cycle: First quenched to Ms>T>MF at a cooling rate faster than the critical cooling rate and held for t > 104 sec, followed by reheating to T > 727 o C and held for a long time, and then quenched to Ms < T < TN at a rate faster than the CCR, and held for t > 104 seconds and then quench to room temperature?

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.

What precautions should you take to prevent injuries when dealing with heavy loads?

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
