Figure 4-9 try a land associated with optimum volume of water vapor per lb of air against air temperature

The X-axis is actually heat. The circular a€?maximum water vapour linea€? is named the a€?saturation range.a€? Additionally it is generally 100% relative dampness, abbreviated to 100per cent rh. Any kind of time point on the saturation range, air keeps 100per cent regarding the water vapour per lb of atmosphere that will coexist with dry air at that temperatures.

If the same amount of environment have best 1 / 2 the weight vapor that it has the capacity to hold at that temperature, we refer to it as 50percent relative humidity or 50% rh. It is shown in Figure 4-10 . Atmosphere any kind of time point on the 50% rh range have half the water vapor the exact same amount of atmosphere might have at this temperature.

As you care able to see from the chart, the maximum amount vapor that moist atmosphere can incorporate increase rapidly with growing temperatures. 4% of their body weight as water vapor. (more…)
