Lewis Ferry Moody

This article is about the engineer Lewis F. Moody; for the English rugby player of the same name, see Lewis Moody .

The Moody diagram shows the pipe friction coefficient as a function of the Reynolds number and the relative roughness.

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

He is known for developing the Moody diagram named after him for calculating the pressure loss in straight pipelines with fully developed laminar or turbulent flow . The diagram describes the relationship between the dimensionless values ​​of the Reynolds number , the relative roughness and the pipe friction coefficient . ${\displaystyle Re}$ ${\displaystyle k/D}$ ${\displaystyle \lambda }$

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

Life

Moody began his work as a professor for hydraulics and machine design in 1930. He developed the Moody diagram , which is important and widespread in fluid technology, in 1944.

He received 23 patents for his inventions, especially in the field of fluid flow machines.

Awards

Moody received two awards for his work.

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

Five years after his death, the American Society of Mechanical Engineers (ASME) presented him with the Lewis F. Moody Award for the first time . The award is presented annually and honors ASME scientists for their outstanding work in the field of mechanical engineering.
