Last part Time to empty a tank 😀😀😀
Now initially , A cylinder of height H , and cross sectional area of cylinder is 'A' , area of orifices is 'a'
let the water came down ' y ' height downward .
we know that , efflux velocity = √ 2gy
Now , through equation of continuity
A.V1= a . v
V1 = a v /A
... Basically it's represents rate of change of ' y ' w.r.t time.
We can write also -dy/dt ..( negative in direction)
So , dy/dt = -(a/A). √ 2gy
Therefore ,
→∫ 1/√y dy (limit from H to 0 ) = -a/A √2g ∫ dt (limit from 0 to t)
→[2√y] ( limit from H to 0 ) = -(a/A). √2g . ∫ dt (limit from 0 to t).
→Applying limit value of integration we get
→2√H =(a/A). √ 2g.t
→t = (A/a) .√2H/ g

😇😇😇Correct me if I am wrong ☺️☺️☺️
Hello 👍👍👍
Correct, absolutely correct

*Please anybody solve the following question by this formula.*
Example 10.7 Blood velocity: The Now of blood in a large artery of an anesthetised
dog is diverted through a Venturi meter The wider part of the meter has a cross sectional area equal to that of the artery A = 8 mm². The narrower part has an area a = 4 mm². The pressure drop in the artery is 24 Pa. What is the speed of the blood in the artery?
direct application of formula !
just have to realize that h = pressure drop / ( rho g )
This is my first comment on youtube. I never comment on anybody's video but this person.just want to say thank you
Best teacher ever known
19:02 question ans is 480 cm³/s or 48 m³/s
