Supercritical, uniform flow of water occurs in a 5.0-m-wide, rectangular, horizontal channel. the flow has a depth of 1.5 m and a flow rate of 45.0 m3/s. the water flow encounters a 0.25-m rise in the channel bottom. find the normal depth after the rise in the channel bottom. is the flow after the rise subcritical, critical, or supercritical? assume frictionless flow

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

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.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
