What is the disadvantage of a dual-entry centrifugal compressor compared to a single-entry centrifugal compressor?

🔍 Key Concepts

• Single-entry vs dual-entry centrifugal compressor basic layout • How airflow path and ducting changes when you add a second inlet • Impact of design complexity on size, speed, and efficiency

💭 Think About

• Compare the physical construction: what has to change when you bring air in from two sides of the impeller instead of one? • Think about whether adding a second entry makes the compressor simpler or more complex in terms of inlet passages and ducting. • Ask yourself: does a dual-entry design naturally force the machine to be bigger, slower, or more efficient—or does it mostly affect how the air gets into the impeller?

✅ Before You Answer

• Identify which option clearly describes inlet/ducting complexity rather than performance numbers. • Check which choices talk about physical size or speed and decide if dual-entry automatically causes those changes. • Be careful with any option that claims greater efficiency—is that always true for dual-entry, or does it depend on detailed design?
