A process stream needs to be cooled with cooling water before being sent to storage. Background. It doesn't have to be table salt, nor does the solvent need to be water. Fouling of heat exchangers has been reviewed [Bott (1990), Hewitt et al. This approach is successfully applied to examples available in the literature. To calculate the limiting temperature, we will use the Excel solver. For example, ˉx ′ 2 = 0 and ˆˉx ′ 2 = 1 means that the heat exchanger works at first in a steady counterflow state and then, at τ = 0, a changeover takes place to the parallel-flow condition. This is then used by the assertThat method Aside from the example above, there are far more methods that can be used to rigorously test one's code. The overall heat transfer coefficient U = 200 W/m 2 K.
