Wishing everyone a happy Children’s Day~~~ The Mechanical Section has introduced the \"One Question per Day\" feature, which not only helps to foster an active atmosphere for technical discussions and guide the direction of such exchanges but also provides users with financial rewards, enabling them to experience various cool features. 【Daily Question】 True or False: For multi-stage centrifugal compressors, to achieve the same pressure ratio, compressing heavier gases requires more variable compression work, which leads to a greater number of stages. Answer: Incorrect. Requirements for responding to the question: Please reply with the answer you believe to be correct, and include any detailed explanations or analyses related to the question. Additional rewards will be given if your answer is correct and your explanations are accurate and thorough. Feel free to answer. Please note: We will close this thread after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation. Do not submit answers repeatedly. As a reward for your effort, if you post a topic in this section within two days that provides a detailed explanation of the knowledge points related to this question, please reply or leave a comment in this post to inform us, and we will have a moderator award you + charm points. It is not allowed to simply copy and paste; original content is preferred, with at least some organization by the user along with personal insights and opinions. After registration, we will rank participants based on the content of their posts: the last-place contestant will receive +1 charm, the second-to-last +2 charm, and so on, with the highest score earning +5 charm.

Error. Happy Children’s Day to everyone: lol
For multi-stage centrifugal compressors, to achieve the same pressure ratio when compressing heavy gases, a greater variable compression work is required; as a result, the number of stages increases by X
Incorrect; the smaller the molecular weight of a gas, the more difficult it is to compress it. To achieve the same pressure ratio, the number of stages can be increased. Variable speed control can be used to accomplish this by raising the speed.
For multi-stage centrifugal compressors, to achieve the same pressure ratio when compressing heavy gases, a greater variable compression work is required, which leads to a larger number of stages. (Mistake)
