Answer:
Explanation:
A well-sealed house means that there is no mass interaction between air indoors and outdoors. Hence, cooling process is isochoric. The heat removed by the air conditioner is:
The power drawn by the air conditioner is:
Answer:
- the mass flow rate of air is 7.53 kg/s
- the exit area is 0.108 m²
Explanation:
Given the data in the question;
lets take a look at the steady state energy equation;
m" = W" / [ (h₁ - h₂ ) -
]
Now at;
T₁ = 900K, h₁ = 932.93 k³/kg
T₂ = 500 K, h₂ = 503.02 k³/kg
so we substitute, in our given values
m" = [ 3200 kW × ] / [ (932.93 - 503.02 )k³/kg -

| ]
m" = 7.53 kg/s
Therefore, the mass flow rate of air is 7.53 kg/s
now, Exit area A₂ = v₂m" / V₂
we know that; pv = RT
so
A₂ = RT₂m" / P₂V₂
so we substitute
A₂ = {[ ×
×
] / [(1 bar)(100 m/s )]} |
||
A₂ = 0.108 m²
Therefore, the exit area is 0.108 m²
Question:
The question is incomplete. The table of value was not added to your question. Below is the table of value and the plotted graph attached.
p R= VCM/AC p/R
0.0001 1 0.0001
0.0005 1.7 0.000294
0.001 3 0.000333
0.005 6 0.000833
0.01 8 0.00125
0.05 10 0.005
Answer:
(a) Yes
(b) W.C = 9.1428
(c) mass of activated carbon = 27.35 Ib-mole/activated carbon
Explanation:
(a) From the graph attached, it is evident that Langmuir isotherm fits the data well. So, the answer is yes.
(b)
Since the input stream has a VCM partial pressure of 0.02 psia, this would be used to find working capacity of activated carbon.
From the graph it can be found by interpolation that p/R value corresponding to 0.02 psia is 0.0021876. Thus R = 9.1428 = WC
It should be noted that in adsorption process, activated carbon is in equilibrium with 0.001 psia of VCM. Thus, from the data R= 1 i.e. this amount of VCM is not adsorbed and lost. This value may be deducted based on the definition of working capacity (WC).
(c)
The molar flow rate of VCM = 1000*62.3*0.02/379*60*14.7
= 0.003739 Ib-mole/hr
Mass of activated carbon required = 0.003739 *8*9.1428*100
= 27.35 Ib-mole/AC
