The reynolds number, pvd/u, is a very important parameter in fluid mechanics. verify that the reynolds number isdimensionless, using both the flt system and the mltsystem for basic dimensions, and determine its value for ethylalcohol flowing at a velocity of 3 m/s through a 2-in.-diameter pipe.

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.
