5.5.3. Steady Flow

Try these first

1. 1.

   Define steady flow in fluid mechanics.

   Hint

   Think about how you would describe water flowing from a faucet consistently.

2. 2.

   What does Bernoulli's equation relate?

   Hint

   Recall the relationship between speed and pressure.

3. 3.

   What defines steady flow?

   • Flow conditions change over time.
   • Flow conditions remain constant over time.
   • Flow is always laminar.

   Hint

   Remember the consistency of flow at specific points.

4. 4.

   Bernoulli's equation accounts for which of the following factors?

   • Only pressure
   • Pressure and height
   • Pressure
   • height
   • and velocity

   Hint

   Think about the three different energy types in fluid.

5. 5.

   Consider a scenario in a water treatment plant where raw water enters a filtration system at a rate of 0.2 m³/s with a velocity of 2 m/s and a pressure of 150 kPa. Calculate the outlet velocity if the outlet diameter is 0.15 m.

   Hint

   Remember the area formula for a circle.

6. 6.

   A fluid flows through a horizontal pipe that bends at a right angle. If the pressure before the bend is 120 kPa and the pipe has an inlet diameter of 0.1 m and outlet diameter of 0.05 m, find the pressure at the outlet.

   Hint

   You may need to calculate velocities based on diameter changes.
