🔍 Key Concepts

• Impulse turbine flow pattern – where does the main pressure drop occur: stationary nozzles or moving blades? • Axial vs. tangential forces – which design feature minimizes net thrust along the shaft? • Purpose of dummy pistons / equalizing holes in turbine rotors

💭 Think About

• First, recall how steam flows through an impulse turbine stage: where is pressure nearly constant, and where does velocity change? • Think about which parts of the rotor or wheel are specifically provided to balance forces on opposite sides of a disc or drum. • Which option describes a feature that directly helps equalize pressure on both sides of the rotor, thereby reducing net axial force?

✅ Before You Answer

• Verify in your notes where the pressure drop occurs in an impulse turbine (nozzles vs. moving blades). • Identify which choices deal with pressure balancing across the rotor rather than just energy conversion. • Ask: which listed feature is explicitly used in turbine design to reduce axial thrust on the rotor?
