Poiseuille's's law for the flow of a liq...

Poiseuille's's law for the flow of a liquid in a capillary tube is given by
`eta=(piDeltaPa^(4))/(8LV)`
where `eta` = co-efficient of viscosity of a liquid `DeltaP` = Pressure difference across a length (L) of a tube of radius (a)
and V = Volume of the liquid flowing per second The maximum error that enters the calculations of `eta` is due to the measurement of

A

L

B

a

C

`DeltaP`

D

V

Text Solution

Verified by Experts

The correct Answer is:
b
Maximum error is introduced in the total error, in the measurement of the radius (a), as we have to consider `(a^(4))`, the fourth power of a.

Three capillaries of lengths l_(1),l_(2) and l_(3) and radii r_(1),r_(2) and r_(3) respectively are joined in series. If p is pressure difference across the combination of capallaries, what will be the volume of liquid flowing per second?

When a liquid moves steadily under some pressure through a horizontal tube, it moves in the form of cylindrical layers coaxial to the ends of the tube. The velocity of different layers is different. The velocity of the layer is maximum along the axis of the tube and it decreases as one moves towards the walls of the tube. According to Poiseuille, the rate of flow of liquid through a horizontal capillary tube varies as the relation V alpha (pr^(4))/(eta l) where l and r are the length and radius of the tube and p is the pressure different between the ends of the tube and is the constant of proportionality. When two capillary tubes through which the liquid is flowing are joined in series then the equivalent liquid resistance is
