Web1 de sept. de 2009 · Case study A from Lewin (1998) consists of 5 hot streams and a single cold stream. Any effective solution will require splitting of the cold stream. The best solution WebOr, it can be divided between cold and streams which mean that the cold stream will be warmer by 5 C and the hot streams will be cooler by 5 C. Finally, it can be decreased from hot streams which in turn mean that the hot stream will be cooled by 10 C. Suppose that we choose the last option, although the hot streams cannot be fully warmed and
