A psychrometer has a dry-bulb reading of 85°F and a wet-bulb reading of 81°F. Find each of the following measurements. (a) relative humidity (%) (b) dew point (°F) (c) maximum moisture capacity of the air (gr/ft3) (d) actual moisture content of the air (gr/ft3)

Step 1
We can use the Goff-Gratch equation for this: $P_s(T) = 10^{\left(10.79574\left(1-\frac{273.16}{T}\right) - 5.028\log_{10}\left(\frac{T}{273.16}\right) + 1.50475\times10^{-4}\left(1-10^{-8.2969\left(\frac{T}{273.16}-1\right)}\right) + Show more…

The air a room has a dry-bulb temperature }\end{array}$ of $75 F and a wet-bulb temperature of 65. Assuming a pressure of 14.3 psia, determine $(a)$ the specific humidity, (b) the relative humidity, and ( $c$ ) the dew-point temperature.
The dry- and wet-bulb temperatures of atmospheric air at 95 kPa are 25 and 17°C, respectively. Determine: (a) The specific humidity, (b) The relative humidity, and (c) The enthalpy of the air, in kJ/kg dry air.
