. Water flows in a streamline manner through a capillary
tube of radius a. The pressure difference being P/2 and the rate of flow is 8 cc per second. If the radius is reduced to r/2 and the pressure is increased to P, then the rate of flow becomes
A: 1 CC/S
B: 2 CC/S
C: 4 CC/S
D: 8 CC/S
Best Answer
Explanation:-
Initial radius of capillary tube r=a;
Initial pressure difference, Δp=p/2.
Final answer:-
Hence, the correct option is(A) i.e. 1cc/s.
