A dimensionally consistent relation for the volume V of a liquid of coefficient of viscosity 
flowing per second through a tube of radius 
and length l and having a pressure difference p across its end, is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Given V = Rate of flow = 
, P = Pressure = 
, r = Radius = [ L ]
= Coefficient of viscosity = 
, l = Length = [ L ]
By substituting the dimension of each quantity we can check the accuracy of the formula 
= 
L.H.S. = R.H.S. i.e., the above formula is Correct .
