🔍 Key Concepts

• Pressure compounded impulse turbine construction and flow path • Purpose of the diaphragm in a multi-stage impulse turbine • How pressure difference across a diaphragm affects axial thrust and steam leakage

💭 Think About

• Think about what happens when you have high pressure on one side of the diaphragm and low pressure on the other side. Which turbine component feels an unbalanced force because of this? • Which of the listed options is specifically used to counter or balance an axial force created by a pressure difference across an area? • Eliminate any options that are more related to holding blades in place or reducing leakage between blade tips and casing, instead of balancing thrust from a pressure drop.

✅ Before You Answer

• Identify which part of the turbine is directly exposed to the pressure difference across the diaphragm and could develop axial thrust. • Check which option mentions equipment used to balance or reduce thrust, not to secure blades or seal blade tips. • Confirm that the chosen option logically connects a pressure drop across the diaphragm with a need to control end thrust on the rotor/shaft.
