4.2.1. Pressure Components and Reynolds Transport Theorems

Try these first

1. 1.

   What does the mass conservation principle state?

   Hint

   Think about a closed system.

2. 2.

   Define what a control volume is in fluid dynamics.

   Hint

   It helps in analyzing fluid motion.

3. 3.

   What does the mass conservation equation state?

   • Mass inflow is greater than outflow
   • Mass inflow equals mass outflow
   • Mass can be created or destroyed

   Hint

   Consider what happens in a closed system.

4. 4.

   Reynolds Transport Theorem is used to calculate what?

   • True
   • False

   Hint

   Think about momentum and fluid interactions.

5. 5.

   A water jet of mass flow rate 8 kg/s and velocity 10 m/s strikes a flat plate. Calculate the total force exerted on the plate assuming all momentum is transferred to the plate.

   Hint

   Think about the relationship between force, mass flow rate, and velocity.

6. 6.

   Consider a tank with inflow of water at 5 kg/s and an outflow of 6 kg/s. Determine if this system is sustainable and explain your reasoning.

   Hint

   Use the mass conservation principle to analyze sustainability.
