Question

Air at *T*_{1} = 32°C, *p*_{1} = 1
bar, 50% relative humidity enters an insulated chamber operating at
steady state with a mass flow rate of 3 kg/min and mixes with a
saturated moist air stream entering at *T*_{2} =
7°C, *p*_{2} = 1 bar. A single mixed stream exits at
*T*_{3} = 17°C, *p*_{3} = 1 bar.
Neglect kinetic and potential energy effects

A) Determine mass flow rate of the moist air entering at state 2, in kg/min. (Answer = 4.5 kg/min)

B) Determine the relative humidity of the exiting stream [%].

Answer #1

please give some positive rating.. i have less cf score.. thank you so much..

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 95°F, 1 atm, and 10% relative humidity enters an
evaporative cooler operating at steady state. The volumetric flow
rate of the incoming air is 1765 ft3/min. Liquid water
at 68°F enters the cooler and fully evaporates. Moist air exits the
cooler at 70°F, 1 atm. There is no significant heat transfer
between the device and its surroundings and kinetic and potential
energy effects can be neglected.
a)Determine the mass flow rate of the dry air in lb(dry
air)/min....

Water at p1 = 20 bar, T1
= 400oC enters a turbine operating at steady state and
exits at p2 = 1.5 bar, T2 =
230oC. The water mass flow rate is 4000 kg/hour. Stray
heat transfer and kinetic and potential energy effects are
negligible.
Determine the power produced by the turbine, in kW, and the rate of
entropy production in the turbine, in kW/K.

A
humid air stream enters a process at 35 C, 20 atm, and 50% relative
humidity. The oxygen flows at 900kmol/h. Determine the molar flow
rate of water in the stream.

Atmosphric air at 40 F and 50% relative humidity enters the heating
section of an airconditioning device at a volumetric flow rate of
100ft^3/min. Water vapor is added to the heated air to increase the
relative humidity to 55%. The temperature after the heating section
is 72F and the temperature at the exit is 74F. Using the
appropriate fomulas:
a) determine the rate of the heat transfer in Btu/min.
b) determine the mass flow of water vapor in lbm/min.

Air from outside (5 deg-C, 50% relative humidity) is heated by
an electrical heater to a temperature of 35 deg-C at a mass flow
rate of 10 kg/s (dry air). Determine the relative humidity of the
conditioned air at the exit

A horizontal portion of a well-insulated ducting for a
ventilation system operating at steady state has one inlet at 35
degrees C with a mass flowrate of 45 kg/min and a second inlet at
21 degrees C with a volumetric flowrate of 30.25 m^3/min. A single
stream exits at 29 degrees C through a 1.1 m diameter pipe. The
pressure for the entire system is 1 atm throughout. Assume air as
an ideal.
a.) Draw a detailed schematic of the...

A mixing chamber has 2 inlets, first, steam water enters at 12
bar and 1173.15 K , then, saturated liquid enters at 12 bar and 80
kg/min. The exit conditions are 12 bar and 120 kg/min. Obtain the
mass flow rate (kg/s) at which steam water enters, the temperature
at the exit (C°) and the quality of substance at the exit. Ignore
the changes of kinetic and potencial energy.

Consider an air-cooled condenser in which a stream of R-134a
enters at 12 bar and 60degC, and leaves as a saturated liquid at 12
bar, and air enters as a separate stream at 1 bar, 35degC and
leaves at 1 bar, 45degC. The two streams do not mix but heat
transfer from one stream to the other stream occurs at the rate of
6.94 kW.
Determine
(a) the mass flow rates for the R-134a and the air (kg/s),
and
(b)...
