Fluid in Motion

Below are the assumptions for fluid flow except:

• All fluids move with streamline flow.

• All fluids move with streakline flow

• Fluids are incompressible

• There is no internal friction

Non-uniform flow is

• when the flow velocity is the same magnitude and direction at every point

• when the velocity is not the same at every point

• the flow from point to point does not change from time to time

• the flow from point to point change from time to time

At a given instant in time the conditions at every point are the same, but will change with time. An example is a pipe of constant diameter connected to a pump; pumping at a constant rate which is then switched off. What is the flow?

In ______________ flow, the fluid flows in layers parallel to each other.

Which statement is correct about transitional flow?

• the flow is very unpredictable and often changeable back and forth

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

• the flow is very unpredictable and often changeable back and forth

Streamline is.....

• A curve formed by the velocity vectors of each fluid particle at a certain

• the angle where the tangent at each point indicates the direction of fluid at that point

• the velocity vector has normal component
