The terms slurry and mixture are used interchangeably to describe a mix of any loose solids, made up in any proportions and combinations of any particle sizes and any conveying liquid. The subscript w refers to densities and specific gravities of liquids – mostly, but not exclusively, water. The letter w has been used in preference to the letter l, because l can be confused with the digit 1. The term water is often used here when the term liquid would be more correct. On the rare occasion when it is essential to differentiate between water and some other liquid, then both w and l should be used as needed. Note that w is also used to designate a function of weight or mass, as in concentration by weight.
The subscript m identifies the density and specific gravity of a slurry. Often, to avoid repetition, the words head of fluid are used in units of head measurement when the word fluid refers to either liquid (when pumping a liquid) or slurry (when pumping a slurry). The subscripts s and d are used to identify pipes, valves, gauges or physical conditions respectively at, or upstream of, pump suction flange and at, or downstream of, discharge flange. The equal sign (=) is used to indicate that the character in the Symbols column is actually a dimension.
