Lewis Ferry Moody

Lewis Ferry Moody (* 1880, † 1953) was an American mechanical engineer and professor of hydraulic engineering at Princeton University.

He is known for the development of the eponymous Moody diagram for calculating the pressure drop in straight pipes with fully developed laminar or turbulent flow. The diagram describes the relationship between the dimensionless values ​​of the Reynolds number, relative roughness and the friction factor.

Moody was the first professor of hydraulic engineering at the faculty of engineering at Princeton University.

Life

Moody began his career as a professor of hydraulic engineering and machine design in 1930. The important and widely used in fluid mechanics Moody diagram he developed in 1944.

For his inventions, especially in the field of turbomachines, he received 23 patents.

Awards

For his work Moody received two awards.

• Elliott Cresson Medal ( 1945)
• Honorary Membership in the American Society of Mechanical Engineers (ASME ) ( 1951)

Only five years after his death in his honor by the American Society of Mechanical Engineers (ASME ) was presented for the first time, the Lewis F. Moody Award. The award is given annually and honors scientists of the ASME awards for its outstanding work in the field of mechanical engineering.
