Exam Focus
- Balance applied pressure against total resistance.
- Recognize beer pumps as added force in high-resistance systems.
- Use flow rate as a draft-system performance signal.
What to know
Flow at the faucet is the practical result of pressure, restriction, and system design.
Syllabus detail
- Applied gas pressure and total resistance determine faucet flow rate.
- High-resistance draft systems may use beer pumps to add force.
Study task
Be ready to explain applied gas pressure and resistance determine flow rate in the context of draft principles and apply it to a realistic Certified Cicerone® service, tasting, brewing, style, or pairing scenario.
Key Terms
- Applied gas pressure
- Balance applied pressure against total resistance.
