The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
1:18 scale is a traditional scale (ratio) for models and miniatures, in which 18 units (such as inches or centimeters) on the original is represented by one unit on the model. Depending on application, the scale is also called two third inch scale since 1 foot is represented by 2/3 of an inch.
The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read 'one centimeter to one meter', 1:100, 1/100, or 1 / 100 . A bar scale would also normally appear on the drawing.
Example: How many standard cubic feet are in 1 cubic foot of gas at 80 °F and gauge pressure 50 psi? (assuming that there is 13.6 psi atmospheric pressure and ignoring super compressibility) V s = 1 cu ft × [(13.6 psi + 50 psi) / 14.73 psi] × [(60 °F + 459.67 °F) / (80 °F + 459.67 °F)]
0.1 × ( 12 ÷ 8 ) = 0.15 grain per dscf when corrected to a gas having a specified reference CO 2 content of 12 volume %. Notes: Although ppmv and grains per dscf have been used in the above examples, concentrations such as ppbv (i.e., parts per billion by volume), volume percent, grams per dscm and many others may also be used.
1:18 scale diecast replicas are 1/18th the size of the real vehicle. Most popular in this category are 1:18 scale automobile replicas – usually made out of Zamak zinc diecasting alloy [ 1 ] with plastic parts. " 1:18 scale" is the colloquial reference to this class of toy or replica.
