🔍 Key Concepts

• straight reaction turbine flow path and how energy is converted from pressure to velocity and then to mechanical work • the role of nozzles, diaphragms, and tip clearances in directing and containing steam (or fluid) in a turbine • difference between gradual efficiency losses (like friction) and sudden or excessive power loss caused by specific faults

💭 Think About

• Think about which component, if it is faulty, would most directly reduce how much of the fluid’s energy actually reaches the blades to do useful work. • Ask yourself: which of these problems is most likely to cause a large, noticeable drop in power rather than just a small efficiency loss? • Consider how the working fluid moves through a reaction turbine: where could it escape or be misdirected so that it bypasses effective energy transfer?

✅ Before You Answer

• Be clear on what a straight reaction turbine is and how it differs from an impulse turbine. • For each choice, picture where in the turbine that fault occurs (nozzle, flow path, packing, blade tips) and how it would affect available energy at the rotor. • Decide which option would cause the greatest immediate loss of useful work, not just minor internal losses.
