Southwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company. Southwest Airlines is breaking ground on a new international terminal in Houston.The Houston terminal is a big part of Southwest's international expansion plans. Houston is the fifth-largest U.S. metropolitan area, so it has plenty of local traffic, and it is well located to serve as a Latin American gateway.outhwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company.

The unit of measuring the brightness-or to use the precise scientific terminology, illuminance-in SI system of measurement is lux or lumen per square meter.Illuminance is measured in foot candles. One foot-candle is equal to 10.76 lux. Please note that lumen is the measure of total light emitted by a source of light.he total amount of visible light is measured in units of lumens. How bright it appears when it falls on a surface area is illuminance. When the same luminous flux falls over a larger area it will appear to be less bright. 1 lx = 1 lm/m^2 which in terms of the basic SI units is 1 cd*sr*m^-2.
A lux meter for measuring illuminances in work places. The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area.It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. flux of 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 lux. However, the same 1000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux.
