QUESTION: 1

At what distance r from center of a pipe of radius R the average velocity is indicated as the local velocity in laminar flow ?

Solution:

QUESTION: 2

In laminar flow through a circular pipe, the discharge varies

Solution:

So,

Q ∝ pressure gradient and Q ∝ R^{4}

QUESTION: 3

For laminar flow through a long pipe, thepressure drop per unit length increases

Solution:

QUESTION: 4

In a steady laminar flow of a given discharge of a liquid through a circular pipe of diameter d, the hydraulic gradient varies

Solution:

QUESTION: 5

The friction factor in the relation h = AfLV^{2}/2gd for laminar flow in a circular pipe was found to be 0.01. This corresponds to a flow Reynolds number equal to

Solution:

∴

QUESTION: 6

The flow profile of a fluid depends upon

Solution:

Reynold number is the factor by which type of flow is decided i.e., laminar or turbulent.

QUESTION: 7

For pipes, laminar flow occurs when reynolds number is

Solution:

For internal flow or pipe flow

(Re)_{Cr} = 2000

i.e. Re < 2000 — Flow is laminar

Re > 2000 — Flow is turbulent

QUESTION: 8

In a two-dimensional flow of a viscous fluid, couette flow is defined for

Solution:

Coutte flow is characterized as flow of very low value of Reynolds number between two parallel

QUESTION: 9

For fully developed laminar flow through a pipe the volumetric flow is given by (symbols have the usual meaning)

Solution:

QUESTION: 10

Capillary tube viscometers used for measurement of viscosity are based on
