Apparatus designed to measure and record the size distribution of raindrops as they occur in the atmosphere.
An instrument for measuring snow hardness in terms of the resistance of snow to the pressure exerted by a disk attached to a spring-loaded rod, a gauge calibrated in pounds per square inch registers the amount of resistance. See Canadian hardness gauge.
A linear imperfection in a crystalline array of atoms. Two basic types are recognized: (1) an edge dislocation corresponds to the row of mismatched atoms along the edge formed by an extra, partial plane of atoms within the body of a crystal; (2) a screw d ...
Agreement given by liner conferrence to a shipper, allowing the shipper to use a non-conference shipping line for a particular consignment.
A machine where a static pressure rise is obtained by allowing successive volumes of gas to be aspirated into and exhausted out of a closed space by means of the displacement of a moving member.
The volume displaced by the compressing element of the first stage per unit of time.
A source of power (electricity) that can displace power from another source so that source's power can be transmitted to more distant loads.
The theoretical speed that a boat can travel without planing, based on the shape of its hull This speed is 1.34 times the length of a boat at its waterline. Also known as hull speed.
The amount of money which an individual has available to spend on inessential items after essential.
The length of fluid flow (gas or liquid) past a sensor required for the sensor to respond to 63.2% of a step change in speed. Expressed in feet or meters. For anemometers, this value is calculated from time constant times wind tunnel speed.
The distance traveled after correction for current, leeway and other errors that may not have been included in the original distance measurement.
Any signal that is used to indicate that a vessel is in distress and needs help. Flares, smoke, audible alarms, EPIRB, electronic beacons and others are all types of distress signals.(2) A flag display or a sound, light, or radio signal calling for assist ...
