A closed system consisting of 0.5 m3 of air at 35°C, 1 bar, and 70% relative humidity is cooled at constant pressure to 29°C. Determine: a. The mass of the air and the mass of the water vapor b. The work for the process c. The heat transfer for the process

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
