Air at a temperature of 20 0C and 750 mm Hg has a relative humidity of 80%. Calculate,
(i)The molal humidity of the air
(ii)The molal humidity of this air if its temperature is reduced to 10 °C and pressure increased to 2000 mm Hg condensing out some of the water
(iii)Weight of water condensed from 1000 litre of the original wet air
Vapour pressure of water at 20 °C = 17.5 mm Hg
Vapour pressure of water at 10 °C = 9.2 mm Hg

If at 30F the air has 25% relative humidity, what is the
relative humidity at 70F and how much moisture must be added to get
it up to 50% relative humidity.

At 200 C relative humidity of 1 m3 of air
is 60%. when temperature is kept constant and volume is reduced to
0.25 m3 find the mass of moist air that would be
condensed.
SVP of water at 200 C = 17.5mmHG R= 8.31 J

I need answers on 3.2.4
3.2.3 If the air temperature is 15°C and the relative humidity
35 percent, calculate the vapor pressure, specific humidity, and
air density. Assume standard atmospheric pressure (101.3 kPa).
3.2.4 Solve Prob. 3.2.3 if the air temperature rises to 300C. By
what percentage does the specific humidity increase as a result of
the temperature rise from 15 to 300C?

In a low temperature drying system, air at 60°C and 10% Relative
humidity passes over a bed of diced carrots at 20 kg-dry air/sec.
The rate of water removal from the carrots Is measured by
difference in total weight over time and found to be approximately
.16 kg-water/sec. In the system described above, calculate the
temperature and relative humidity of the air exiting the drying
system.

300% excess air having a dry bulb temperature of 25 degree
celsius and relative humidity of 60% is used to fully combust 1
kg/hr of methane in a boiler and the heat of reaction is used to
generate steam. Hot water enters the boiler as a saturated liquid
at 102 degree celsius and leaves as superheated at 40 bar and 400
degree celsius.
The combusted gases leave the boiler at 450 degree celsius and
are then cooled to 25 degree...

Moist air at 55 oF dry bulb temperature and 40% relative
humidity is first heated through a heating coil. The air is then
adiabatically humidified by saturated water vapor at 4.5 psia. The
exit air has a dry bulb temperature of 90 oF and wet bulb
temperature 65 oF. Air is supplied at a volume flow rate of 478.5
cfm. Assume sea level pressure throughout. Determine the
following.
a) Show the inlet and outlet air condition clearly on the
psychrometric...

Relative humidity isn't everything. Why is it that outdoor air
of 80 Fo at 55% humidity will feel more “muggy” than a 50 Fo cave
at 75% humidity? What other parameter is a better measure of the
actual amount of moisture in the air, and how do we define it? Then
give two examples of when keeping close track of moisture in the
air is important.
