8.4(a) is a variant of the calandria evaporator in which the steam chest is contained in a basket suspended in the lower part of the evaporator, and recirculation occurs through the annular space round the basket. Figure 8.4 Evaporators (a) basket type (b) long tube (c) forced circulation.all slender vertical tubes may be used for evaporators as shown in Fig. 8.4(b). The tubes, which may have a length to diameter ratio of the order of 100:1, pass vertically upward inside the steam chest.
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus.
Mitosis is a method of cell division in which a cell divides and produces identical copies of itself. The primary mechanism by which organisms generate new cells is through cell division. During this process, a single âparentâ cell will divide and produce identical daughter cells. In this way, the parent cell is able to pass on its genetic material to each of its daughter cells. First, however, the cells must duplicate their DNA. Mitosis is the process by which a cell segregates its duplicated DNA, ultimately dividing its nucleus into two.
