Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. Multiple-choice question: Which of the following design methods for the condensate pipes in high-pressure steam heating systems are correct? ( ) (A) The condensate pipe before the trap should not rise upward. (B) The height to which the condensate pipe rises after the trap must be determined through calculation. (C) In a condensate pipeline that relies on the residual pressure of the trap, the minimum backpressure after the trap should not be less than 50 kPa. (D) The steam-condensate pipe from the trap to the return water side should be designed taking into account the presence of steam-water emulsions. A new activity has started in the production area; the prizes are attractive, so hurry and participate: 【Production Through Summer】 – The production area has entered the “training during the hot summer days” mode
