Q

With regards to fluid flow control, an advantage of pneumatic control systems over electrical control systems is __________.

🔍 Key Concepts

• pneumatic control systems vs. electrical control systems (how each one behaves when power is lost) • how compressed air is stored and used in control systems • the meaning of terms like power available, transmission losses, and energy input in practical shipboard systems

💭 Think About

• Think about what happens to a control system that uses compressed air if the ship suddenly loses electrical power for a short time. Can the system still operate using stored energy? • Which of the options sounds too perfect to be realistic in any system (for example: unlimited power, zero losses)? • In real engine room practice, what is the main reason many safety and control devices (like some valves and actuators) are designed to be air-operated instead of fully electric?

✅ Before You Answer

• Eliminate any option that suggests no losses at all or unlimited power, since all real systems have limits and losses. • Ask yourself which choice is most clearly linked to the presence of stored compressed air in receivers or accumulators. • Verify which advantage would matter most in an emergency or blackout situation on board.
