3. 5 kmol of Propane gas initially at 373.15 K (100 °C) and 1 bar is compressed to final state of 423.15 K (150 °C) and 10 bar. Estimate: a. Z, HR , UR , SR , GR at the initial state and final state using virial equation sate truncated into two terms and generalized correlation to determined B. b. Hig and Sig c. H, S, U, and G for the prescribed change of state. 4

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.
