5.1. Reservoir case with V = 0

Try these first

1. 1.

   What happens to Bernoulli's equation when the fluid velocity is zero?

   Hint

   Think about what terms drop out.

2. 2.

   What is the relationship between pressure and elevation in a reservoir?

   Hint

   Consider the basic hydrostatics concept.

3. 3.

   What is assumed when fluid velocity is zero in a reservoir?

   • Only pressure matters
   • Both pressure and elevation matter
   • Bernoulli’s principle does not apply

   Hint

   Think about what terms in Bernoulli's equation can be ignored.

4. 4.

   True or False: Bernoulli’s equation can be applied across different streamlines.

   • True
   • False

   Hint

   Recall the assumptions for applying Bernoulli’s equation.

5. 5.

   A reservoir has water 15 meters above a discharge point. Using Bernoulli's equation, calculate the velocity of the water as it exits.

   Hint

   Remember to use the correct value for g.

6. 6.

   Consider a setup where a pipe makes a 10 cm diameter opening at the base of a large tank filled with water. If the water level is maintained at 20 m, calculate the flow rate when the height difference to the outlet is 2 meters.

   Hint

   Calculate the area from the diameter first and then relate it to flow.
