The 'Moody’s Chart' is used to determine the ______.
-
A.
Reynolds number
-
B.
friction factor in pipe flow
-
C.
hydraulic radius
-
D.
velocity of flow
Correct Answer:
B. friction factor in pipe flow
Explanation:
The Moody’s chart is a widely used graphical representation in fluid mechanics that illustrates the relationship between the Darcy-Weisbach friction factor, Reynolds number, and relative roughness for fully developed flow in circular pipes. By using this chart, engineers can determine the friction factor, which is essential for calculating pressure drops and head loss caused by friction within a piping system. It effectively maps out different flow regimes, including laminar, transitional, and turbulent flow, providing a reliable method for analyzing pipe flow characteristics.
