17.2.2. Data Given

Try these first

1. 1.

   What is the condition for a flow to be considered incompressible?

   Hint

   Consider what the Mach number represents.

2. 2.

   In a flow system, if density is constant, how does it simplify calculations?

   Hint

   Recall the term volumetric flux.

3. 3.

   What is the maximum Mach number for a flow to be considered incompressible?

   • 0.1
   • 0.3
   • 0.5

   Hint

   Recall the definition of incompressible flow.

4. 4.

   True or False: Incompressible flow assumes density remains constant.

   • True
   • False

   Hint

   Think of how density behaves under low compressibility.

5. 5.

   A cylindrical tank is filled with water from two different outlets. Given the outlets have different flows, calculate the change in water height after a specified time considering the tank's dimensions.

   Hint

   Make sure to check how the outflows affect the overall tank height.

6. 6.

   Observe a river confluence where two streams meet. Given their velocities and widths, will the water level rise or fall downstream? Calculate the effect based on flow rates.

   Hint

   Think about how mass balances apply to the junction of the streams.
