Figure shows the top view of a tube
Are the pressures and velocites of the fluid at points 1 and 2 same?
(1 and 2 r along same radial line)
explain ur ans.
i hav an explanation for both the parts:
1.Pressure cant be same bcoz the wen the fluid moves along the curved part, it
has centripetal acceleration. The force for this can come only by pressure variation
2. a=v^2/r
were a is radial acc. and r is radius of curvature .
as streamlined flow acceleration has to be same for all points in fluid??
so v^2 proportional to r.
so v2>v1
This is the ans for the second part but
an entirely different explanation was given .
Am I missing something?
