n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

large, flat ocean floor, usually near a continent and usually over 4km (13100 ft) ss.

n: a clutch containing an inflatable tube that, when inflated, causes the clutch to engage the driven member. When the tube is deflated, disengagement occurs.

inflatable devices in a pipeline meant to stop flow.

n: 1. a flat-decked, shallow-draft vessel, usually towed by a boat. Barges are not self-propelled. They are used to transport oil or products on rivers, lakes, and inland waterways. Also, a complete drilling rig may be assembled on a barge and the vessel used for drilling wells in lakes and in inland waters and marshes. Similarly, well service and workover equipment can be mounted on a barge. 2. an offshore drilling vessel built in the shape of a ship. Unlike a ship, however, it is not self-propelled. Also called a drill barge.

marine vessel without its own propulsion.

n: I. the fore and aft reference line at the upper surface of the flat plate keel at the centre line for flush shell plate vessels. 2. the thickness of the garboard strake above that level for vessels having lap seam shell plating.

a weld technique on diagonal cut strips of steel, superior to the butt weld process for joining flat strips of metal together before rolling into coiled tubing.

n: a wire rope that has been flattened and the strands of which have been spread. v: to flatten and spread the strands of a wire rope.

a flat bottom, short steel tool run on wireline to tag the surface of water or solids in the well. It is nearly the drift diameter of the tubular.

usually a flat bottom mill.
