Saturated liquid water enters the boiler at a pressure of 70 bar, and saturated vapour enters the turbine. The condenser pressure is 0.06 bar. The engine runs on a carnot circle. Determine : The thermal efficiency,​

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.
