The tool life decreases from 0.8 min to 0.2 min due to the increase in cutting speed from 60 m/min to 120 m/min in a turning operation.
Compute is the value of the cutting speed at 0.4 min.
a-)Determine the spindle speed in rpm.
b-)Find the required power for the unit force.
c-)The friction between tool and workpiece varies 0.25-0.35 during the process.
d-)Calculate the rate of maximum force to minimum force.

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.
