The air at the entrance to a grain dryer is 40.0 ° C and 20.0% RH. The debit

is 300.0 L / s. The dryer extracts 7,000 kg / h of grain water. The air temperature at

dryer outlet is 30.0 ° C. What is the relative humidity (%) of the air leaving the dryer?

The total pressure everywhere is 101.3 kPa.

Yes debit means flowrate of air entering.

using given data and phychromertic chart we can find the exit Rh of air

for any doubts write in comments

Air entering a dryer has a temperature (dry bulb) of 60°C and a
dew point of 26.7°C. Using the humidity chart, determine the actual
humidity H, percentage humidity HP, humid heat cS and humid volume
vH.

Humid air is enclosed in a 5.00-liter flask at 40.0°C. The flask
is slowly cooled. When the temperature reaches 20.0°C, drops of
moisture become visible on the flask wall. Although the pressure in
the flask changes when the temperature drops, it remains close
enough to 1 atm for the psychrometric chart to provide a close
representation of the behavior of the system throughout the
process. Use a psychometric chart to determine the relative
humidity, absolute humidity, and wet-bulb temperature of...

How much moisture per pound of dry air is removed by air
entering moist grain at 110 degrees F dry bulb temperature and
exiting the grain at 90% RH and 68 degrees F wet bulb?

Dry thermometer temperature of 65.6C , air entering a
dryer
Its dot is 15.6ºC. Using the humidity chart, the humidity
value of the air (kgH2O / kg
k.air) and percent humidity (%). The volume of moist air (ısı)
and heat
Find the capacity (????) values. Results must be in the SI
unit system.

Moist air (RH = 60%) at 80oF enters an Evaporative
cooling unit as it enters a greenhouse and leaves at 100%
saturation.
How many pounds Water per pound of Air will be required?
Select one:
a. 0.0155 lbs H2O per lb Air
b. 0.002865 lbs H2O per lb Air
c. 0.028656 lbs H2O per lb Air
d. 0.01315 lbs H2O per lb Air
e. 0.002344 lbs H2O per lb Air

The following description applies to the next three
problems.
Air enters steadily an electrical hair dryer at 100 kPa and 27
C. It leaves the hairdryer at a temperature of 80 C, an exit
velocity of 10 m/s, and at the same pressure. The exit and inlet
areas are 20 cm2 and 40 cm2 respectively.
(Assume properties of air cp= 1.007 kJ/kg.K, cv = 0.72 kJ/kg.K,
and R= 0. 287 kJ/kg.K )
The mass flow rate of air entering the...

The air quantity at 25 oC and 80% RH required for
complete combustion for refuse (dry basis) is 7.0 lb/10000 Btu. Air
supplied for complete combustion is 30% in excess.
please find the volume of air at 25 oC and 80% RH
needed for complete combustion (30% excess)

Two long, parallel transmission lines 40.0 cm apart carry 20.0 A
and 80.0 A currents.
1)Find all locations where the net magnetic field of the two
wires is zero if these currents are in the same direction.
Enter your answer as two distances in centimeters, the
first distance from the wire carrying 20.0 A, and the second
distance from the wire carrying 80.0 A. Separate the values with a
comma.
2)Find all locations where the net magnetic field of the...
