Lesson 8 - Control of Fluid Flow 1

This lesson considered two main classifications of pumps: centrifugal and positive displacement. These were introduced together, with aspects of their design and operation. The lesson also pulled together various fluid mechanics concepts from previous lessons, such as the Darcy-Weisbach equation and the use of loss-coefficient to calculate pressure drops in pipe systems. It then used this information to then size pumps for particular pipe systems.

You should now be able to:

1. Describe the principles of operation of centrifugal and positive displacement pumps.

2. Recommend pump types for different brewery applications.

3. Discuss the various criteria used to define pump performance.

4. Describe the principle of matching a pump performance to a piping system requirement using the pump-curve approach and apply this principle to simple situations.

5. Describe the approaches of flow rate control and pump starting procedures.

A self-assessment lesson now follows, which will allow you to determine the level to which you have attained the above outcomes.
