Is a technique for predicting whether water will tend to dissolve or precipitate calcium carbonate. If the water precipitates calcium carbonate, scale forming may result. If the water dissolves calcium carbonate, it has a corrosive tendency.

A day for general ship cleaning.

The principal sail that is set on the main mast.

The wind speed and direction in an undisturbed flow.

Replenishment at Sea.

A movement of electrons in an external circuit connecting an anode and cathode in a corrosion cell; the current flow is arbitrarily considered to be in an opposite direction to the electron flow.

See 'allocation.

An electrical depth sounder or fish finder that uses sound echoes to locate the depth of objects in water. It does so by timing the sound pulses.

A suitable beach, being steep and sandy, where ships could be careened for cleaning or repair.

An opening such as a hole or vent. An opening through which air can pass, or a restricted opening placed in a pipe line to provide a means of controlling or measuring flow.

The maximum current density that can be used to obtain a desired electrode reaction without undue interference such as from polarization.

The eutectic of the iron-carbon system, the constituents of which are austenite and cementite. The austenite decomposes into ferrite and cementite on cooling below the temperature at which transformation of austenite to ferrite or ferrite plus cementite i ...
