ABSTRACT
ENGER 05.05. 1881 Decorah IA/USA 13.05. 1956 Escondido CA/USA Melvin Lorenius Enger was educated at University of Minnesota and University of Illinois, where he gained the BS degree in 1906 and the MS degree in civil engineering in 1916. He was from 1908 an instructor at his Alma Mater, from 1911 assistant, from 1917 an associate, and from 1919 professor of theoretical and applied mechanics. Further, from 1934 to 1949 he was the director of its Engineering Experiment Station. Enger was a member of the American Water Works Association AWWA and the recipient of its 1940 Goodell Prize, the Western Society of Engineers WSE, the American Society for Testing Materials ASTM, and the American Society of Engineering Education ASSE, among others. Enger dealt with a wide range of questions relating to engineering design and research. The 1918 work relates to discharge coefficients of orifices in which a small effect of scale was found provided the head on the orifice or the orifice opening are too small. This finding was in agreement with many others then conducted worldwide. The 1929 paper deals, as one of the first, on manifolds, an element widely used in industries, heating and distribution techniques. The topic has also application in lock design, furnaces or wastewater treatment stations, but the systematic investigation initiated only in the 1950s. Enger and his colleague therefore made an early study on these flows found in collecting or distributing systems. Further research was directed toward flow resistance through locomotive water columns, penstock design, pressure transmission in granular material, or air inlet valves for pipelines.
