Question

i m maths student i dont know anything abt dynamics can anybody help me in it i want to know equation of continuity in fluid dynamics

Answer 1

The equation of continuity is quite simple. Suppose water flows in a pipe. Where the pipe is narrow, it flows at a greater velocity due to higher pressure, and where it is broader, it flows slower.
So the area of cross section of a pipe appears to be inversely proportional to the velocity of the fluid flowing there.
From your maths class, u must remember that if two quantities are inversely proportional to one another, their product is constant.
A1*v1=A2*v2
**The liquid is considered to be incompressible. That means, due to pressure its density should not change/
Hope u got it.
