化工导论到目前为止都还是一样很废 再加上大家都说话导的成绩是乱数的 所以 超想翘课的~ 但是,昨天突然觉得老师可能会点名 就乖乖去上课了 没想到 老师最後发了一张作业 下礼拜要交 但因为份数不够 所以我只多拿了一张 想要印的话可以找我或詹皓安 题目如下: (一) A wet paper pulp is found to contain 71% waterby weight. After drying, it is found that 60% of the original water has been removed. Calculae the following: (a)The composition of the dried pulp (b)The mass of water removed per kilogram of wet pulp. (二) The Sun-moon Lake can be visualized as a large cylindrical tank with 1000m in diameter and 10m in depth. The water flowing into the lake is at a rate of 10000Kg/s and contains 1g NaCl/Kg of water. If pure water is evaporated on the surface at 5g/sm^2 , what is the rate of water flowing out of the lake and its composition if it is to maintain at steady state? 对了,我问了化工系班代,他说他没有考古题,也没听别人讨论过考古题 而且问了另一个化工系的同学,不过他也说他不知道~ 超怪的~~ 不过他会帮我们问一下 就降~ --
