It was further determined that if one calculates the Roman foot from the quadrantal, the cube equal to 80 librae of water, and the libra is calculated from the sample weights, one obtains a foot that goes from the length of the pes Aebutianus to a maximum of about 131.8. Paris lines (297.3428 mm.).
Crystallization is also a chemical solidâliquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer.
A scraped surface crystallizer consists of a jacketed pipe in which a cooling medium between the pipe wall and the jacket remove heat from the slurry, causing crystallization. Inside the pipe, large scrapers wipe the solid deposits from the wall to prevent build up.
