Lewis Ferry Moody (5 January 1880 – 18 April 1953) was an American engineer and professor, best known for the Moody chart, a diagram capturing relationships between several variables used in calculating fluid flow through a pipe. He states that his goal is to present a simple and convenient means for engineers to estimate the friction factor inside the new pipes and conduits running full with steady flow.Moody, Lewis F., Friction Factors for Pipe Flow, Transactions of the A.S.M.E., Nov. 1944, page 671 He has 23 patents for his inventions.iplexl.com - Petents list for Moody, Lewis Ferry He was the first Professor of Hydraulics in the School of Engineering at Princeton.princeton.edu - Description of Acquisitions by the Princeton University Library , princeton.edu - Aerospace and Mechanical Sciences, The Department of
Biography He was born on 5 January 1880.
Lewis F. Moody as professor of fluid mechanics and machine design taught at Princeton University starting in 1930.aiaa.org - Aerospace Education and Research at Princeton University, 1942–1975 He co-wrote the book Fifty Years’ Progress in Hydraulics with fellow engineer Blake R. Van Leer.
He married Eleanor Greene. His wife died in 1937. His daughter, Eleanor Lowry Moody, married in 1944. He was awarded the Elliott Cresson Medal in 1945.
He was elected an Honorary Member of the American Society of Mechanical Engineers (ASME) in 1951.asme.org - Honorary Members
He died on 18 April 1953.
Legacy Five years after his death, ASME created an Award to his honours: The Lewis F. Moody award, which is awarded for outstanding original papers useful to the practice of mechanical engineering by the Fluids Engineering Division (FED).asme.org - Lewis F. Moody award
