This paper presents results of an experimental program to determine loss coefficients for several flat oval elbows, i.e., 90[degrees] easy bend elbows
, mitered 90[degrees] easy bend elbows
with and without vanes, and mitered 90[degrees] hard bend elbows
with and without vanes.
Keeping the back fairly straight, slowly bend elbows
behind you about 5 or 6 inches and then straighten.
so hands are at shoulder height, palms facing out.
, keeping them close to body bringing weights toward shoulders, push up over head until arms straight again.
