Water falls from a tap with 
, 
and 
, then volume rate at velocity v is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As water falls from a tap, the velocity of water goes on increasing, hence from the equation of continuity, the cross-section of water-stream goes on decreasing. If 
is area of cross-section of the mouth of the tap and 
is the velocity of water at this point and 
are corresponding quantities at depth h, then
(volume rate of flow)
and
