打家豪,本次中油煉製類有親戚朋友參加考試,對答案的時候有些疑問但是沒有人能夠討論,他沒有ptt帳號所以人家幫他詢問一下啦o'_'o
煉製類專業科目第33題:
「下列何種方式無法增加熱交換器的總熱傳係數?」
(A)提高熱交換器的流體速率
(B)於相同的操作條件下,增加鰭管熱交換器中鰭片之數量
(C)於相同的操作條件下,增加殼管熱交換器中檔板之數量
(D)於相同的操作條件下,增加夾套熱交換器中夾套的寬度
這題官方答案是D,當事人是選B
但是他找到之前九十四年度四技二專的考題有類似的題目:
「鰭管熱交換器 ( fin tube heat exchanger ) 是藉由下列何種方式提高傳熱速率?」
(A)增強熱擾流
(B) 增加傳熱面積
(C)加速熱量循環
(D)增加總熱傳係數
正確答案是B
想知道這次33題答案是他哪裡搞錯了還是題目答案有問題
有人可以解惑一下嗎o'_'o?
我是都看不懂啦,是我的話我會猜C
第一次發文有點緊張
能幫忙解惑的願意給一點點p幣表示感謝
