🔍 Key Concepts

• how steam (or fluid) hits turbine blades at high speed • the effect of moisture droplets in the steam flow • how vacuum at the turbine exhaust affects steam velocity and condensation

💭 Think About

• Think about what physically wears away metal from a turbine blade surface—what has to be present in the steam for erosion to occur? • Consider whether any one factor alone is enough, or whether several conditions acting together would increase droplet impact and erosion. • Ask yourself: does a higher exhaust vacuum change the speed and phase (wet/dry) of steam at the last-stage blades?

✅ Before You Answer

• Verify which options increase the number and impact speed of liquid droplets striking the blades. • Consider how last-stage low‑pressure blades are affected differently than high‑pressure stages. • Check whether each factor listed (speed, moisture, vacuum) tends to make the steam wetter and faster at the blade tips.
