Horizontal tube of non-uniform cross-seed. has radii of 0.1 m and 0.05 m respectively at M and N. For a streamline How of liquid, the rate of liquid flow is
A) changing continuously with time
B) greater at M than at N
C) greater at N than at M
D) same at M and N
Correct Answer:
C
Solution :
Not Available from equation of continuity \[{{A}_{1}}{{V}_{1}}={{A}_{2}}{{V}_{2}}\]therefore velocity of fluid at N is greater than that at M.
