Drilling Speeds and Feeds UFL MAE
Drilling Speeds and Feeds . The speed of a drill is measured in terms of the rate at which the outside or periphery of the tool moves in relation to the work being drilled. The common unit and term for this velocity is surface feet per minute, abbreviated sfm. Every tool manufacturer has a recommended table of sfm values for their tools.

A high viscosity ratio between the skewed liquid water and the local water vapor layer adjacent to the wall is essential to achieving a large slip length and therefore a high level of drag reduction. Given that the viscosity ratio for water (at T w = 91°C) and its saturated vapor is approximately μ l /μ v = 25 ( 47 ) and that the fitted slip ...

Transmission (mechanics) Wikipedia
Often the term transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device. In British English, the term transmission refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rearwheel drive), differential, and final drive shafts.

Compression Ratio Calculator CRT Performance
Compression Ratio is an important variable in building a performance engine. In general, higher compression ratios mean more horsepower. Compress the air/fuel mixture into a smaller volume (increasing compression ratio) and you've got a mixture that's easier to ignite, burns quicker and more completely, and hence delivers more power.
