Water flow through a horizontal pipe whose internal diameter is `2.0 cm` at a speed of `1.0 ms^(-1)` What should be the diameter of the nozzle, If the water is to emerge at a speed of `4.0ms^(-1)`?

A

1cm

B

2cm

C

0.5 cm

D

1.5 cm

Text Solution

Verified by Experts

The correct Answer is:
B
From the equation of continuity
`A_1v_1=A_2v_2`
`:." "pi(d_1^2)/4v_1=pi(d_2^2)/4v_2`
`:." "d_2^2=d_1^2((v_1)/(v_2))=1/4(0.02)^2=10^(-4)m^2`
`:." "d_2=10^(-2)m=1cm`
