12.3.2. Resultant Velocity Magnitude

Try these first

1. 1.

   What happens to velocity in a converging nozzle?

   Hint

   Think about conservation of mass.

2. 2.

   Define local acceleration in fluid flow.

   Hint

   Focus on one location.

3. 3.

   What occurs to fluid velocity when the area decreases in a nozzle?

   • It decreases
   • It remains constant
   • It increases

   Hint

   Remember the mass conservation.

4. 4.

   True or False: Local acceleration depends on the position in the flow.

   • True
   • False

   Hint

   Consider how velocity could change at a specific location.

5. 5.

   Given a converging nozzle with varying diameters, derive the expression for velocity at different sections of the nozzle based on the principle of conservation of mass.

   Hint

   Utilize the continuity equation for incompressible flow: A1V1 = A2V2.

6. 6.

   In a specific flow, compute the pressure difference resulting from velocity change, given Bernoulli's principle.

   Hint

   Consider energy conservation in the system.
