🔍 Key Concepts

• Huddling chamber safety valve design and purpose • How steam pressure and area interact to create lifting force • Difference between velocity effects and pressure acting on surfaces

💭 Think About

• Which part of the valve actually creates additional lifting force once the disc has just started to open? • Is the continued opening mainly caused by speed of steam flow, direction of flow, or pressure acting over a larger effective area? • How does the shape of the disc, lip, or ring change the area that steam pressure can act upon after initial lift?

✅ Before You Answer

• Identify what a huddling chamber does compared with a plain safety valve • Determine which option describes steam pressure acting over a changed or enlarged effective area, not just flowing faster • Eliminate any options that focus only on external piping or reactive/jet forces rather than the internal valve geometry
