🔍 Key Concepts

• Short cycling in pump control systems • How pressure tanks/accumulators smooth demand in potable water systems • Difference between pump speed control and stored pressure/volume

💭 Think About

• Which option would store pressurized water so that the pump does NOT need to start every time a small faucet is opened? • Which choices describe ways to run the pump differently, and which choice adds another component to the system? • In a typical ship’s domestic fresh water system, what device keeps pressure relatively constant between pump starts and stops?

✅ Before You Answer

• Identify which option actually provides volume under pressure to the system, not just changes pump speed or flow. • Think about which device allows multiple small water uses before the pump needs to start again. • Confirm which component is commonly called an accumulator or pressure tank in potable water systems.
