The power required to drive such a bridle is (T 2 – T 1) ⋅ (R + h/2) ⋅ ω, i.e. (T 2 – T 1) ⋅ v. where v is the strip speed in m/sec; h is the strip thickness in meters; R is the radius of the Bridle Rolls in meters and; ω is the Bridle's angular speed in radians per second. The electrical power required by the drive motor = volts ...
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
Two very commonly used loss functions are the squared loss, () =, and the absolute loss, () = | |.The squared loss function results in an arithmetic mean-unbiased estimator, and the absolute-value loss function results in a median-unbiased estimator (in the one-dimensional case, and a geometric median-unbiased estimator for the multi-dimensional case).
Curve fitting [1] [2] is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, [3] possibly subject to constraints. [ 4 ] [ 5 ] Curve fitting can involve either interpolation , [ 6 ] [ 7 ] where an exact fit to the data is required, or smoothing , [ 8 ] [ 9 ] in which a "smooth ...

These regulators normally compensate for tank pressures between 30–200 pounds per square inch (2.1–13.8 bar) and commonly deliver 11 inches water column 0.4 pounds per square inch (28 mbar) for residential applications and 35 inches of water column 1.3 pounds per square inch (90 mbar) for industrial applications. Propane regulators differ ...
Excel 2.0 was released a month before Windows 2.0, and the installed base of Windows was so low at that point in 1987 that Microsoft had to bundle a runtime version of Windows 1.0 with Excel 2.0. [129] Unlike Microsoft Word, there never was a DOS version of Excel.
Threaded pipe and elbow.The pipe has a male NPT thread, while the elbow is female.. American National Standard Pipe Thread standards, often called national pipe thread standards for short, are United States national technical standards for screw threads used on threaded pipes and pipe fittings.
