A baymouth bar completely separates the bay from the ocean and is formed in much the same way that a spit is formed, through deposition caused by the longshore drift. The sediments that make up spits come from a variety of sources including rivers and eroding bluffs, and changes there can have a major effect on spits and other coastal landforms. D.

What does bars mean? Most bays have streams flowing into them, and since this water has to get out, it is rare that a baymouth bar will completely close the entrance to a bay. \begin{array}{l}{\text { tube } \mathrm{OD}=1.905 \mathrm{cm}} \\ {\text { tube } \mathrm{ID}=1.656 \mathrm{cm}} \\ {\text { steam saturation temperature }=319.5 \mathrm{K}} \\ {\text { steam latent heat, } h_{f g}=2393 \mathrm{kJ} / \mathrm{kg} \text { .
