Two water pipes of diameters 2 cm and 4 ...

Two water pipes of diameters 2 cm and 4 cm are connected with the main supply line. The velocity of flow of water in the pipe of 2 cm

A

4 times that in the other pipe

B

`(1)/(4)` times that in the other pipe

C

2 times that in the other pipe

D

`(1)/(2)` times that in the other pipe

Text Solution

Verified by Experts

The correct Answer is:
A
AV = Constant `implies (V_(1))/(V_(2))=(A_(2))/(A_(1))=(d_(2)^(2))/(d_(1)^(2)),(V_(1))/(V_(2))=(4^(2))/(2^(2))=4`
