23. Introduction to Fluid Dynamics

Try these first

1. 1.

   What is the Bernoulli equation used for?

   Hint

   Think about the properties of fluids that change with motion.

2. 2.

   Define steady flow in fluid dynamics.

   Hint

   Consider the concept of time in relation to fluid characteristics.

3. 3.

   What does Bernoulli's equation relate?

   • Pressure
   • Temperature
   • Pressure
   • Velocity
   • Height
   • Temperature
   • Volume

   Hint

   Think about the components involved in fluid motion.

4. 4.

   True or False: Bernoulli's equation can be applied in regions of steady flow only.

   • True
   • False

   Hint

   Consider the definition of steady flow.

5. 5.

   A water tank has a height of 5 meters. Using Bernoulli's equation, calculate the velocity of water exiting through a hole at the tank's base. Assume atmospheric pressure and no viscosity.

   Hint

   Remember to use the relationship between potential energy and kinetic energy.

6. 6.

   In a pipe, the diameter decreases from 0.5m to 0.2m. How does Bernoulli's equation help you explain the pressure difference?

   Hint

   Consider the principles of flow rate continuity and energy conservation.
