    The ideal water potential between fresh water (right) and sea water (left) corresponds to a hydraulic head of 270 metres. Pressure retarded osmosis (PRO) is a technique to separate a solvent (for example, fresh water) from a solution that is more concentrated (e.g. sea water) and also pressurized.

    Several systems of dimensioning and tolerancing have evolved. The simplest dimensioning system just specifies distances between points (such as an object's length or width, or hole center locations). Since the advent of well-developed interchangeable manufacture , these distances have been accompanied by tolerances of the plus-or-minus or min ...
