Economic Effects of Mineral Content in Municipal Water Supplies (open access)

Economic Effects of Mineral Content in Municipal Water Supplies

Report describing the application of conventional cost experience to physical features of source of supply, treatment, pumping, transmission, distribution, and storage for community water supply sources. Some costs due to readily removable water quality characteristics like suspended solids, color, taste, and order are measurable, as are other conventional costs of operation and maintenance. Other costs related to an excess of dissolved solids, however, tend to be unknown and are the subject of this study.

Temperature Distribution in the Crystallization of Undercooled Liquids in Cylindrical Tubes (open access)

Temperature Distribution in the Crystallization of Undercooled Liquids in Cylindrical Tubes

From Introduction: "The major difficulty in interpreting the results obtained by this simple experimental technique is the specification of the temperature at the crystal-liquid interface. Since, the liquid-to-solid transformation is exothermic the temperature in the vicinity of the interface will exceed the temperature in the vicinity of the interface will exceed the temperature of the bulk of the cooling bath, which is the quantity most conveniently measured and most frequently reported."
