21.1.3. Pressure at B (Using Bernoulli’s Equation)

Try these first

1. 1.

   What does Bernoulli's equation describe?

   Hint

   Think about energy forms in moving fluids.

2. 2.

   Give an example of a major loss.

   Hint

   Consider factors affecting fluid movement.

3. 3.

   What principle does Bernoulli's equation represent?

   • Flow Conservation
   • Energy Conservation
   • Mass Conservation

   Hint

   What happens to energy in a moving fluid?

4. 4.

   True or False: Minor losses are always negligible.

   • True
   • False

   Hint

   Consider scenarios where fittings are numerous.

5. 5.

   Calculate the pressure at point B if total head loss is 15m and initial pressure is 200kPa. Assume no velocity at point B.

   Hint

   Use the pressure drop due to head loss.

6. 6.

   A pipe has a length of 500m, diameter of 0.5m, and a friction factor of 0.02. Calculate the major head loss.

   Hint

   You'll need flow velocity information to proceed.
