🔍 Key Concepts

• Axial thrust produced by reaction vs. impulse turbines • Effect of single-flow vs. double-flow arrangements on thrust balance • How turbine design can self-balance or require separate thrust‑balancing devices

💭 Think About

• Which type of turbine stage (impulse or reaction) tends to create more continuous axial thrust in the direction of steam flow? • How does arranging steam to flow in two opposite directions through the rotor affect the net axial thrust? • In which arrangement would the net thrust naturally cancel out, and in which would you need an added device like a dummy piston or cylinder to balance it?

✅ Before You Answer

• Identify which options are single flow and which are double flow • Recall that double-flow designs are usually chosen to help balance axial thrust without extra devices • Remember that reaction stages generally develop more axial thrust than impulse stages; consider where that extra balancing might be needed
