For an oil reservoir , calculate the following for a vertical oil well considering steady state Porosity, Phi=0.25 Permeability, k=20 md thickness, h=40 ft Reservoir pressure, Pe=5,000 psi Bubble point pressure, Pb=100 psi Area, A=500 acres Skin, S=5 Total Compressibility, Ct=0.0000125 psi-1 Oil Viscosity, mo=1.5 cp, wellbore radis, rw=0.33 ft Time=30 days

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.
