🔍 Key Concepts

• Potable water system pressure control on ships • Difference between pump speed control and stored energy (air or water) in tanks • How pressure is smoothed when demand (usage) suddenly changes

💭 Think About

• If several faucets and showers are opened and closed quickly, what part of the system could absorb those rapid changes and keep pressure from fluctuating? • Which option works even when the pump is not changing speed at all? • Which device can store energy (in the form of compressed air or elevated water) to supply short bursts of water without a big drop in line pressure?

✅ Before You Answer

• Identify which choices involve active pump control vs. passive pressure storage/smoothing • Think about which device continues to help maintain pressure when the pump is off or between cycles • Ask: which option is most commonly paired with the term hydro-pneumatic tank in ship potable water systems?
