TURNER H.M.

TURNER H.M. 06.08. 1885 Wareham MA/USA 06.05. 1975 Marblehead MA/USA Howard Moore Turner obtained the AB degree from Harvard University, Cambridge MA, in 1906, and the SB degree in civil engineering there in 1907. He was until 1910 with a construction company, was until 1911 research engineer with a gas company at Easthampton MA, returning until 1917 as hydraulic engineer to the Turners Falls Power & Electric Co., Turners Falls MA, taking there over as assistant of its president at Boston MA until 1918. After service in World War I, he became until 1923 member of an engineering firm at Boston MA, from when he had his private practice at Boston MA, dealing with works in hydraulic engineering and water power projects. He served in parallel as a professor on the practice of engineering at Harvard University. Turner was member of the Boston Society of Civil Engineers, taking over in 1943 as president. He also was member of the American Society of Civil Engineers ASCE, and the New England Water Works Association NEWWA. Turner was in the 1940s identified with important public utility hydro-electric works and developments and other engineering projects. He had been for 20 years intimately associated with Harvard University, where he lectured on water power engineering from the practical view. From 1950, he was involved in the improvement of the Cambridge water system. After years of study under his guidance as president of the Cambridge Water Board, the city approved his plan. This provided for a new pumping station, extensions for water treatment facilities at the filtration plant, work on the sedimentation basins, and a new general shop building. He also was in charge of water projects and other works in hydraulics. Anonymous (1943). Boston civil engineers elect Turner president. Engineering News-Record 130(Apr.15): 529. P Anonymous (1948).

TUTTON 10.05. 1851 Tunkhannock PA/USA 19.06. 1908 Buffalo NY/USA Charles Harold Tutton graduated from Rensselaer Polytechnic Institute, Troy NY, in 1872 as a civil engineer. After works with two railways companies until 1874, he was engaged until 1882 in mining and general engineering at Wilkes Barre PA and at Buffalo NY, where he stayed until his death. From 1882 to 1888 he was engaged in the Lehigh Valley Railroad, in connection with canals, coal trestles, and the shore protection along Lake Erie. From 1893 he was connected with the Engineering Bureau, Buffalo NY, where he had charge of city dredging operations, river improvements, the design of the new city water works, and designing the sewer system. Tutton was a successful engineer who contributed a number of articles to the technical press. At his time, the flow of water in pipes was investigated by both researchers and engineers, given the importance in practice. Despite the effects of roughness and of viscosity on pipe discharge were known, no general formula allowed yet to estimate the main flow parameters. A final answer came only in the 1930s based on the experiments of Ludwig Prandtl (1875-1953) and Johann Nikuradse (1894-1979) in Germany, and the two Englishmen Cyril Frank Colebrook (1910-1997) and Cedric Masey White (18981993), who successfully identified the relative sand roughness height and the Reynolds number as the governing pipe flow parameters. In his discussion on the 1902 paper by Gardner S. Williams (1866-1931) and George H. Fenkell (1873-1949), Tutton presented the then very recent theory of Joseph V. Boussinesq (1842-1929) on turbulent flow of water. He erroneously deduced that the velocity profile of water flow in pipes should be of elliptical shape, however. Further developments led him to the definition of a flow formula, of which particular cases included these of Manning or Dupuit. Anonymous (1909). Charles H. Tutton.
