1. A process of supplying to an operation a liquid that is applied at the operation comprising:
delivering to the operation from a holding vessel a liquid comprising more than one constituent;
applying the liquid at the operation, whereby a spent liquid is formed;
returning the spent liquid to the holding vessel;
analyzing the composition of the liquid at the holding vessel while the liquid at the holding vessel is being delivered and applied at the operation and the spent liquid is being returned to the holding vessel;
determining the amount of each constituent of the liquid that is required to be added to the liquid at the holding vessel to provide at the holding vessel a liquid of a prescribed composition;
delivering to a pressure vessel the amount of each constituent that is required to be added to the liquid at the holding vessel so as to form at the pressure vessel a constituent volley that comprises a combination of each constituent that is required;
increasing the pressure in the pressure vessel to a level adequate to deliver the constituent volley to the holding vessel upon the release of the pressure; and
releasing the pressure from the pressure vessel so as to cause the pressure at the pressure vessel to forcibly deliver the constituent volley to the holding vessel.
