A nozzle in an impulse turbine functions to __________.

Question 1 of 27070

A nozzle in an impulse turbine functions to __________.

🔍 Key Concepts

• Impulse turbine vs. reaction turbine – how energy is extracted from steam • Role of a nozzle in changing steam pressure, velocity, and direction • Difference between thermal energy (heat/pressure) and kinetic energy (motion) of steam

💭 Think About

• In an impulse turbine, what must happen to the steam before it strikes the moving blades to effectively do work? • Does a nozzle primarily slow steam down, speed it up, reverse it, or just direct it with no change in energy form? • Which component in an impulse turbine mainly changes the form of energy, and which component mainly receives that energy to rotate the shaft?

✅ Before You Answer

• Identify which choice describes speeding up the steam versus slowing it down • Decide which options describe a change in energy form (thermal to kinetic or kinetic to thermal) rather than just changing direction • Remember that in an impulse turbine, most of the pressure drop happens in the nozzles, not across the moving blades
