Determine the average convection heat transfer coefficient, convective heat transfer rate, and drag force associated with an L 2-m-long, w 2-mwide flat plate for airflow and surface temperatures of Ts 50C and 80C.

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.
