24.. Bernoulli Equation and its Applications

Try these first

1. 1.

   What is the Bernoulli Equation?

   Hint

   Think about the conservation of energy in fluid dynamics.

2. 2.

   Define static pressure.

   Hint

   Imagine the pressure felt when diving into a still pool.

3. 3.

   What does the Bernoulli Equation relate?

   • Pressure and temperature
   • Pressure
   • velocity
   • and elevation
   • Velocity and force

   Hint

   Remember, it’s all about energy in motion.

4. 4.

   True or False: Stagnation pressure is higher than static pressure.

   • True
   • False

   Hint

   What happens when fluid comes to rest?

5. 5.

   A fluid flows through a venturi meter with inlet and throat diameters of 10 cm and 5 cm respectively. If the inlet velocity is 2 m/s, calculate the velocity at the throat using Bernoulli’s Equation and the continuity equation.

   Hint

   Remember to do area calculations first!

6. 6.

   A water pipe maintains a static pressure of 200 kPa, and dynamic pressure from flow is 50 kPa. Calculate the stagnation pressure.

   Hint

   Recall the stagnation pressure formula!
