FLUID FLOW

Question 1

The flow in which the velocity of fluid is constant at any point

Answer 1

STEADY FLOW

Question 2

When the flow is unsteady, the fluid velocity differs between any two points.

Answer 2

UNSTEADY FLOW

Question 3

flow velocity has the same magnitude and direction at every point in the fluid.

Answer 3

UNIFORM FLOW

Question 4

If at a given instant, the velocity is not the same at every point the flow.

Answer 4

NON-UNIFORM FLOW

Question 5

do not change with position in the stream or with time.

Answer 5

STEADY UNIFORM FLOW

Question 6

change from point to point in the stream but do not change with time.

Answer 6

STEADY NON-UNIFORM FLOW

Question 7

At a given instant in time the conditions at every point are the same, but will change with time.

Answer 7

UNSTEADY UNIFORM DLOW

Question 8

Every condition of the flow may change from point to point and with time at every point.

Answer 8

UNSTEADY NON-UNIFORM FLOW

Question 9

All the particles proceed along smooth parallel paths and all particles on any path will follow it without deviation.

Answer 9

LAMINAR FLOW

Question 10

The particles move in an irregular manner through the flow field.

Answer 10

Question 21

This theorem states that whenever there is a continuous flow of liquid the total energy at every section remains the same provided that there is no loss or addition of the energy.

Answer 21

Bernoulli’s theorem
