Generally the usual depth of first watering in crop field is required as:
a)3" inches in a ploughed field
b)9" inches in a ploughed field
c)12" inches in a ploughed field
d)1" inches in a ploughed field

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

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.
