1.2. Implications of Uniform Flow

Try these first

1. 1.

   Define uniform flow in your own words.

   Hint

   Think about how velocity behaves in such conditions.

2. 2.

   What does non-uniform flow indicate?

   Hint

   Consider how velocity varies in practical scenarios.

3. 3.

   What characterizes uniform flow?

   • A. Varies over distance
   • B. Constant parameters
   • C. Varies with time

   Hint

   Consider how changes in velocity behave in uniform flow.

4. 4.

   True or False: Non-uniform flow means velocities are the same at all points.

   • True
   • False

   Hint

   Reflect on what non-uniform means.

5. 5.

   Consider a fluid flowing in a channel where the velocity is uniform at 12 m/s. If the cross-sectional area of the channel at one point is 2 m², calculate the flow rate. Now, determine the flow rate if the velocity decreases to 8 m/s at the same cross-section.

   Hint

   Remember the formula for flow rate.

6. 6.

   Explain how the no-slip condition affects the design of a penstock in a hydroelectric dam. What design elements would you consider to account for non-uniform flow?

   Hint

   Think about how friction may alter the expected flow rates.
