🔍 Key Concepts

• Identify which major gas turbine section is shown in area C (intake, compressor, combustor, or turbine) based on its position between B and D. • Recall what happens to the pressure of the working fluid during the main heat‑addition process in a gas turbine (Brayton cycle). • Distinguish between fundamental physical laws (like Newton/Bernoulli) and thermodynamic cycles (like Otto/Brayton) when describing how a specific component operates.

💭 Think About

• First, use the overall flow path from left to right (inlet → compressor → combustor → turbine → exhaust) to decide what function the section at C must serve. • Ask yourself: in that section, is the primary purpose to compress air, add heat, extract work, or direct flow? That will narrow down which principle or cycle best matches. • Compare where constant‑volume versus constant‑pressure combustion occurs: which one is typical of reciprocating engines and which of gas turbines?

✅ Before You Answer

• Confirm that the component in area C is correctly identified by its location between the compressor section and the turbine section. • Check which option describes the normal heat‑addition process for a gas turbine rather than a piston (reciprocating) engine. • Make sure you are not mixing up a general law of motion/flow with the specific thermodynamic process that occurs in this section.
