🔍 Key Concepts

• Impulse vs reaction turbines – where does the main pressure drop occur? • Pressure compounding vs velocity compounding – do you see several pressure drops or one big one with several velocity changes? • How fixed blades vs nozzles are arranged across multiple stages in the illustration.

💭 Think About

• Look carefully at the pressure graph at the top: does the steam pressure drop only once, or in several distinct steps as it passes through the turbine? • Compare the velocity graph with the blade layout: where does the velocity increase sharply, and how many times does that happen relative to the nozzles and moving blade rows? • Ask yourself whether each pressure drop is followed by just one row of moving blades, or by several rows with guide (fixed) blades between them.

✅ Before You Answer

• Identify how many separate pressure drops you can clearly see in the pressure diagram and where they occur. • Determine whether the moving blades are arranged as single rows after each nozzle or in multiple rows between fixed blades for each pressure drop. • Confirm whether the turbine action is purely impulse (pressure drop only in nozzles, nearly constant across moving blades) or if there is any sign of pressure drop across the moving blades (reaction).
