An articulated five-platform rail car that allows containers to be double stacked. A typical stack car holds ten 40-foot equivalent units (FEU's).

The interaction between the stages of a centrifugal compressor. When a multi-stage compressor is designed, each stage can operate at only one point its characteristic curve. The point is determine by the design conditions of temperature, flow and pressur ...

A rail service whereby rail cars carry containers stacked two high on specially operated unit trains. Each train includes up to 35 articulated multi-platform cars. Each car is comprised of 5 well-type platforms upon which containers can be stacked. No cha ...

The tendency of the sunlight to electricity conversion efficiency of amorphous silicon photovoltaic devices to degrade (drop) upon initial exposure to light.

A graduated scale placed in a position so that the stage of a stream may be read directly from it. Staff gauges may be placed on bridge piers or pilings, etc., or placed on specially constructed supports.

The elevation of the water surface in a stream as measured by a river gauge with reference to some arbitrarily selected zero datum.

Steps in the compression of a gas, In reciprocating compressors, each stage usually requires a separate cylinder, in dynamic compressors, each requires a separate rotor disc.

A condition that can occur in a solar collector if the working fluid does not circulate when sun is shining on the collector.

Elevated structure from which coal and other cargoes can be loaded into a vessel. Name is also given to a landing-place, or loading-place.

In reference to a wind turbine, a condition when the rotor stops turning.

(1) To stop moving. (2) Usually air travels smoothly along both sides of a sail, but if the sail is not properly trimmed, the air can leave one of the sides of the sail and begin to stall. Stalled sails are not operating efficiently.

The turbulent effect of air on the lee side of a sail when trimmed in too far.

The maximum rope tension (in kilonewtons), measured at the drum exit when the drum ceases to rotate in the direction of haul, the prime mover being set for maximum torque and the rope being wound on the drum in a single layer.

Said of a vessel that is firm, strong, and unlikely to develop leaks.

A vertical support for guardrails and lifelines.
