A1-m by 1-m vertical plate is exposed to saturated water vapor at 1 atm. if the surface of the plate is maintained at 20°c and the mass flow rate of the film is 1 kg/s (use the following property for saturated liquid water60°c and 1 atm: 4.63 x 104 kg/m-s), the flow condition is (a) turbid (b) transition (c) laminar (d) turbulent

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.
