3.1. Application in Turbo Machinery

Try these first

1. 1.

   What is the principle of conservation of mass?

   Hint

   Think about mass flow rates into and out of a container.

2. 2.

   Define the continuity equation.

   Hint

   How do we express inflow and outflow in relation to each other?

3. 3.

   What does the Reynolds transport theorem relate?

   • Momentum conservation only
   • Energy conservation only
   • Mass and momentum conservation

   Hint

   Consider the fundamental connections in fluid dynamics it covers.

4. 4.

   True or False: The continuity equation states that the flow rate into a control volume must equal the flow rate out.

   • True
   • False

   Hint

   Visualize the fluid entering and leaving a container.

5. 5.

   A fluid flows through a pipe with varying diameter. How do you apply the continuity equation to find flow velocities at different points?

   Hint

   Remember to consider how cross-sectional area impacts velocity.

6. 6.

   Calculate the force exerted on a wall by a hydraulic jet of diameter 5 cm flowing at 15 m/s if the fluid density is 1000 kg/m³.

   Hint

   You may need to compute the area first for flow calculations.
