Q

Nozzle diaphragms are installed in pressure-compounded impulse turbines to __________.

🔍 Key Concepts

• Impulse turbine construction – fixed nozzles vs. moving blades and where each is located • Pressure-compounded staging – how pressure drop is divided between stages using diaphragms • The physical role of a diaphragm in a turbine casing (what it mechanically supports or holds)

💭 Think About

• In a pressure-compounded impulse turbine, where does the main pressure drop actually occur – in the fixed nozzles or in the moving blades? How does the diaphragm help make that happen? • Think about what part of the turbine must be held rigidly in place between stages so that steam can be directed correctly onto the next set of moving blades. • Does a diaphragm normally move with the rotor, or is it a stationary part of the casing that carries something else?

✅ Before You Answer

• Identify whether a diaphragm is stationary or rotating hardware inside the turbine. • Match each option with what a diaphragm physically could do (can it really "support moving blades" or "eliminate losses"?). • Focus on which option best describes a stationary structure between stages that carries nozzles and directs steam in a pressure-compounded turbine.
