Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, a series of topics such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Engineering Thermodynamics”, and “Chemical Process Technology” will be introduced. We hope for your active participation! For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! You get 2 wealth points just for participating, and an additional 3 wealth points if you answer correctly~~~ Multiple-choice question: What is the function of the bottom valve in the suction pipeline of a centrifugal pump? A. Preventing solid particles in liquids ； B. Avoid cavitation ； C. Maintain the minimum allowable suction height ； D. Prevent the liquid filled before startup from leaking out of the pump ； B
