Figures 10.23(a) and (b) refer to the steady flow of a (non-viscous) liquid. Which of the two figures is incorrect? Why?
Answers
Hey Hello Champ
Well steady flow a fluid means that the velocity of all the particles at a particular point is always constant. That is if we take a snapshot at a particular instant and then we again take a snapshot after certain time then both the snapshots taken will appear to be same
It follows the equation , A1V1=constant
where,
A=area V=volume
Note :- product of AV gives you the rate of flow of the fluid through a cross section
Now as the area decreases the velocity of the liquid increases hence in figure "a" at the first tube hole the area is very large so the velocity is very small and thus the magnitude of velocity decreases and thus this allows the water to flow more in random direction , while at the second tube hole the velocity is very high and hence the magnitude in a particular direction is also very large and thus water has less chance to flow in random direction hence considering these reasons fig "a" is incorrect while figure "b" is correct
Hope this helps !! ^_^
