🔍 Key Concepts

• Net positive suction head (NPSH) and why it matters for preventing cavitation or vapor binding in pumps • How a main condenser and its vacuum are connected to the feed system on a steam plant • What happens when the space above the impeller eye is connected to a low-pressure or vent point

💭 Think About

• Which part of the feed system can help keep water in a liquid state even at high temperature? • Think about which choice actually affects the pressure at the pump suction/eye, not just at the discharge side. • Which option would help remove or prevent entrained steam/vapor from accumulating in the pump casing?

✅ Before You Answer

• Identify which answer directly improves suction conditions/NPSH at the pump, rather than just discharge pressure control. • Consider which component in the system operates under vacuum and could be used to vent any steam from the pump. • Eliminate choices that only talk about discharge pressure and do not change the conditions at the pump eye/suction.
