Steam at 100°C is blown into an airstream at 21°C dry bulb, 50% saturation (Relative humidity), at the rate of 1 kg steam/150 kg dry air. What is the final condition and show the process on the psychrometric chart? (Ans. Final moisture content (W2 = 0.0148 kgv/kg ; Final dry bulb temperature Tdb2=22.02°C ).

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.

USE EXCEL OR MATLAB IF YOU NEED
Given the dry-bulb temperature, Tdb and
relative humidity, Φ, the wet-bulb, Twb
temperature may be calculated from the psychrometric equation
(Jones, 1994):
PvsΦ – Pss =
PatmA (Twb
-Tdb )

Use your input from the Table below.
The input Twb and Tdb are in oC
(used in Eqs. (2) and (3) in Kelvin).
Pss = saturated vapor pressure at
Twb (kPa)
Pvs = saturated vapor pressure at
Tdb (kPa)

Moist air at 30 °C and 50% relative humidity enters a
dehumidifier operating at steady state with a mass flow rate of
319.35 kg/min. The moist air passes over a cooling coil and water
vapor condenses. Condensate (condensed water) exits at 10 °C.
Saturated moist air exits in a separate stream at the same
temperature. The pressure remains constant at 1 bar. Determine (a)
the rate at which water is condensed, in kg/min, and (b) the heat
transfer rate during...

Air at 28 °C, 1 bar, 50% relative humidity enters an insulated
chamber operating at steady state with a mass flow rate of 5 kg/min
and mixes with a saturated moist air stream entering at 4 °C, 1 bar
with a mass flow rate of 8 kg/min. A single mixed stream exits at 1
bar. Determine
(a) the relative humidity and temperature, in °C, of the exiting
stream.
