Law of motion is quadratic equation and is use in calculate of object trajectory. Fluid dynamic for sizing of pump is also second order equation. Quadratic equation or higher may use to fit equation for fast calculation of result.

Example on vapour density equation for the use of evaporative mass transfer. We do need to know how much water air can take. It could use the data from table but the work will be lengthly. We can make data in the table a form of polynomial equation and so put it into program for calculated out this require vapour density.
