Question 1 of 27070

Leakage over the ends of the blade tips, as a result of the pressure differential between each row of blades in a reaction turbine, can be reduced with a blade design known as ________.

🔍 Key Concepts

• Reaction turbine blade tip leakage caused by pressure difference between the pressure and suction sides of the blade • How designers reduce flow around/over the blade tips instead of through the blade passages • The role of special tip features that act like a seal between blade tip and casing

💭 Think About

• Which option best describes a design that would block or restrict fluid leaking over the blade tips? • Look at the words: which one sounds like it specifically addresses sealing or tightening the space at the blade ends against leakage? • Is the question asking for a general concept that could include several methods, or the specific recognized term for limiting tip leakage in a reaction turbine?

✅ Before You Answer

• Focus on the tip-clearance leakage issue: what kind of design would reduce clearance or act like a seal? • Check whether any option is a commonly used term in turbine design textbooks for tip-leakage reduction. • Be careful with option D (Any of the above): only pick this if you are sure all three are valid, recognized methods to reduce blade tip leakage.
