Question

1. the automatic water feed for a steam boiler:

options:

• is located at the high point in the system
• should not have a check valve
• is part of the boiler feed pump system
• must be operated manually
• is designed to keep the receiver full

Explanation:

To solve this, we analyze each option:

• "Is located at the high point in the system": Automatic water feeds for steam boilers are typically at low points (for water collection), so this is wrong.
• "Should not have a check valve": Automatic water feeds do have check valves to prevent backflow, so this is wrong.
• "Is part of the boiler feed pump system": The automatic water feed is part of the boiler feed pump system that supplies water to the boiler, this is correct.
• "Must be operated manually": It's automatic, so this is wrong.
• "Is designed to keep the receiver full": Its main role is to supply water to the boiler, not just keep the receiver full, so this is wrong.

Answer:

C. Is part of the boiler feed pump system
