The actual amount of water vapor and oxygen in the atmosphere normally declines with an increase in altitude because of the decrease in pressure, so these graphs apply from sea level to around 1 km altitude. The water absorption coefficient indicates, how many kg of water per hour one square meter of material absorbs through capillary action. The water absorption coefficient is used to measure the rate of moisture absorption of building materials. Absorption coefficient of water vapor proposed to be responsible for an increase in temperature in the troposphere layer with altitude less than 10 km is systematically presented in this work.

The data from transmission measurements across water layers of known thicknesses shows that the effective absorption coefficient of These water absorption coefficient are energy-saving products and also easy to operate. These water absorption coefficient are CE, ISO, ROHS certified for authenticity. Browse through the massive water absorption coefficient ranges at and save you money on these purchases. These efficient machines are available as OEM orders and Absorption coefficients for 200 nm and 900 nm are almost equal at 6.9 m −1 (attenuation length of 14.5 cm). Very weak light absorption, in the visible region, by liquid water has been measured using an integrating cavity absorption meter (ICAM). The mass of water absorbed, divided by the horizontal area of the base of the specimen (g/m2) (Y) is plotted on a chart against the square root of time (X) until the rising water reaches the top of the sample. The slope of this straight line (A) is relative to capillary absorption and is called the water absorption coefficient by capillarity.
