🔍 Key Concepts

• Look at how steam absolute pressure changes as it passes through the part labeled nozzle in the graph at the top of the illustration. • Consider what happens to steam absolute velocity in the same region of the diagram. • Think about the different roles of nozzles, fixed blades, and moving blades in a steam turbine: which one actually turns the rotor?

💭 Think About

• In the section marked nozzle, is the pressure mainly dropping, or is the velocity mainly dropping? What does that say about which type of energy is being changed? • Which component in the drawing is clearly responsible for spinning the shaft: the nozzle or the moving blades? So which component is more directly associated with mechanical energy? • If steam speeds up as it passes through a narrowing passage while pressure drops, what kind of energy is it gaining, and what kind is it losing?

✅ Before You Answer

• Verify which of the answer choices describes pressure (potential energy) changing into velocity (kinetic energy). • Confirm that the moving blades, not the nozzle, are the primary parts that convert steam energy into shaft rotation (mechanical energy). • Eliminate any option that suggests the nozzle’s main job is to slow the steam down or to increase its pressure.
