18. Fluid

Try these first

1. 1.

   What is the Reynolds Transport Theorem?

   Hint

   Think about how fluid properties behave at boundaries.

2. 2.

   Define steady flow in fluid mechanics.

   Hint

   Consider a river: is the flow steady or does it change?

3. 3.

   What theorem relates changes in fluid properties to flow across a control volume?

   • Newton's Law
   • Bernoulli's Principle
   • Reynolds Transport Theorem
   • First Law of Thermodynamics

   Hint

   Think about how we track changes in fluid behavior.

4. 4.

   Fluid flow is classified as steady or unsteady based on what?

   • True
   • False

   Hint

   Consider how a river might change.

5. 5.

   A tank has water flowing in at a rate of 2 liters per second. If it has a cross-sectional area of 0.5 square meters and is draining out at a rate of 1 liter per second, find the change in water level over time.

   Hint

   What is the relationship between volume, area, and height?

6. 6.

   Given a T-joint in a pipe system with diameters of 4 m (inlet), 4 m (outlet Q), and 2 m (outlet R), with velocities of 6 m/s and 5 m/s, find the velocity at outlet R.

   Hint

   Remember how mass flow rates tie the velocities together.
