Question
The cylindrical tube of a spray pump has a radius R, one end of which has n fine holes, each of radius r. If the speed of flow of the liquid in the tube is v, the speed of ejection of the liquid through the hole is : -
Options
A.
B.
C.
D.
Solution
According to equation′s of continuity
A1v1 = A2v2
(πR2) v = n (πr2) v′ ⇒ v′ =
A1v1 = A2v2
(πR2) v = n (πr2) v′ ⇒ v′ =
