Question
The diagram (figure) shows a venturesome, through which water is flowing. The speed of water at X is 2 cm/s. The speed of water at Y (taking g = 1000 cm/s2) is : -
Options
A.23 cm /s
B.32 cm/s
C.101 cm/s
D.1024 cm/s
Solution
V22 = V12 + 2gh = (2)2 + 2 × 1000 × 5.1 × 10-1 = 1024
V2 = 32 cm/s
V2 = 32 cm/s
