With a laboratory scale, the tare weight is the mass of the flask and the net weight is the mass of the contents. This can be useful in computing the cost of the goods carried for purposes of taxation or for tolls related to barge, rail, road, or other traffic, especially where the toll will vary with the value of the goods carried (e.g., tolls on the Erie Canal).
N 2 chart example. [1] The N 2 chart or N 2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.
ATM encompasses both airspace and ground airport operations. Since the rise of computer sciences, risk management and decision-making are software-assisted. Recent system developments balance interests of airspace and runways on one side, and capacity overloads for taxiway network and terminals on the other.
A vehicle with a GVM up to 4,500 kg is termed a light vehicle, while those over 4,500 kg are termed heavy vehicles. Many models of small trucks are manufactured to have a GVM rating of 5,000 to 7,000 kg (11,023 to 15,432 lb) but sold with the option of a GVM of just under 4,500 kg so that they can be driven on a car licence.

Air traffic flow management (ATFM) is the regulation of air traffic in order to avoid exceeding airport or air traffic control capacity in handling traffic (hence the alternative name of Air Traffic Flow and Capacity Management – ATFCM), and to ensure that available capacity is used efficiently.
The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.
0.986923 atm The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar).
Campbell Diagram of a steam turbine. Analysis shows that there are well-damped critical speed at lower speed range. Analysis shows that there are well-damped critical speed at lower speed range. Another critical speed at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to ...
