Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring, adjacent to each other.
Calculate the water evaporated n each evaporator, assuming that the fraction of water in the feed removed in each evaporator is the same. Then, develop a linear model of a flow sheet with N evaporators, assuming that the fractional recovery of wat..
