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. Multiple-choice question: Based on the characteristic curve of a centrifugal pump (without a hump), it can be seen that as the flow rate increases, the head ( ) A. increases, B. remains unchanged, C. decreases, D. increases or decreases within a certain range. Answer: C. Please note: We will close this thread after 24 hours, and at that time we will announce the best response (the most helpful answer), along with the correct answer and its explanation. Charisma Reward: Those who post a topic in this section within two days to provide a detailed explanation or discussion of the knowledge points related to this question are asked to reply/comment in this post to inform us, and we will award extra charisma 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.
