A 20mg多巴胺加入200ml氯化钠：

20mg多巴胺为2ml

混合液中每5.05ml=（200ml+2ml）×0.5mg/20mg中含有多巴胺0.5mg

20滴约1ml，那么，每分钟需要滴5.05ml×20滴/1ml=101滴

以设定的速度，需要40分钟=（200ml+2ml）×1分钟/5.05ml就可以滴完

B 20mg多巴胺加入300ml氯化钠：

混合液中每7.55ml=（300+2）×0.5/20中含有多巴胺0.5mg

20滴约1ml，那么，每分钟需要滴7.55ml×20滴/1ml=151滴

以设定的速度，需要40分钟=（300ml+2ml）×1分钟/7.55ml就可以滴完
