We study the problem of preparation of sucrose syrups másicas volumes and compositions determined from volumetric measurements, common problem in many industries especially the food and beverage industry. Under these conditions are imposed certain mass concentrations and volumes that are difficult to prepare from preexisting syrups, due to nonideal behavior of the sucrose-water solution, which causes the volumes are not additives, with the additional feature that industry mainly provides volumetric measurement systems (tank levels, pumps, flow meters, flow), and no mass. An equation for the density of sucrose-water binary solutions is derived based on percentage mass concentrations and temperature from an equation of density volumetric concentration dependent and temperature available in the technical literature. This equation, which is based on measurement data densities sucrose-water solutions of high quality, with little error is transformed into one that uses másicas variables that best fits their application in industry. The extensive processing required is handled in a suitable manner by using computer algebra packages and digital computers, yielding relatively simple equations consisting from a thermodynamic point of view and easily mounted and friendly simple applications intended for use in plants.
