Maximum Water-Vapor Partial Pressure: Above, we assumed a water-vapor pressure of 0.3632 psia. Look this pressure up in the Saturation Steam Table Handout and find its corresponding temperature. Did you find that this is the saturation pressure for 70F, signifying the air is saturated, meaning the maximum partial pressure of water vapor has been reached and no more water vapor can be mixed with air. Reversing the situation, what is the maximum water-vapor partial pressure of moist air at 90F ? psia. Relative humidity ( RH ) of moist air at T and P is defined as the ratio of the actual watervapor partial pressure to the maximum partial pressure (saturation pressure at temperature T from a steam table). What is the RH for Prob. 6 air . Next, calculate the following: Relative humidity (seen on TV) is 70% and the temperature is 90F. What is the actual partial pressure of water vapor in the air? (ans: 0.489 psia). (note: you found Pmax in the previous
