Question

7. State & explain rate of flow of liquid. What is the equation of continuity?​

Answer 1

that 2 pics are the answers of rate of flow of liquid...

first pic is the starting answer

equation of continuity= A1V1= A2V2

this is your answer ❣️

Answer 2

rate of flow of liquid is designated by letter Q.

$q = \frac{volume \: flowing}{time}$

dv is the volume flowing in a particular interval of time

$dv = avdt$

where a is area

v is velocity of water

dt is the instant.

now,

$q = \frac{avdt}{dt}$

which finally gives us

$q = av$

and that my friend is called equation of continuity. av is constant quantity you can find many question in which you have to compare the two av's
