The flow of liquid through a tapering pipe at a constant rate is

12.

Which of the following statement is correct?

(a)	In a compressible flow, the volume of the flowing liquid changes during the flow.
(b)	A flow in which the volume of the flowing liquid does not change, is called incompressible flow.
(c)	When the particles rotate about their own axes while flowing, the flow is said to be rotational flow.
(d)	all of the above

13.

A 1-dimensional flow is one which

(a)	is uniform flow
(b)	is a steady uniform flow
(c)	takes place in straight lines
(d)	involves zero transverse components of flow

14.

Continuity equation deals with the law of conservation of

15.

An ideal flow of any fluid must fulfill the following

16.

The continuity equation

\frac{\partial u}{\partial x} + \frac{\partial v}{\partial y} + \frac{\partial w}{\partial z} = 0

is valid for

(a)	ideal fluid flow only
(b)	incompressible fluids, whether the flow is steady or unsteady
(c)	steady flow, whether the fluid is compressible or incompressible
(d)	incompressible fluids and steady flow only

17.

For the flow of an incompressible fluid, the velocity component in the x-direction is

u = a x^{2} + b y

and the velocity component in the z-direction is zero. The velocity component in the y-direction would be

18.

The component of acceleration due to non-uniformity of flow is called

19.

Local acceleration in fluid flow is due to

(a)	unsteady nature of the flow
(b)	non-uniformity of the flow
(c)	turbulence in the flow
(d)	irrotational nature of the flow

20.

In the case of steady and uniform flow, the total acceleration is
