An incompressible liquid is flowing through a horizontal pipe as shown in figure. Find the value of v.

Text Solution

Verified by Experts

By equation of continuity
AV = constant
`:. A_(1)V_(1) = A_(2)V_(2) + A_(3)V_(3)`
`Axx4` = `0.8 Axx3 + 1.5Axxv`
4A = 2.4A + 1.5AV
4 = 2.4 + 1.5V
v = `1.6/1.5 ~= 1.1`m/s
