(a)
Interpretation:
Rate of air and oxygen flow in mol/s unit should be calculated.
Concept Introduction:
Let us assume
Component material balance equation will be used to determine rate of air flow and oxygen flow.
(b)
Interpretation:
Rate of heat transfer for this mixing process should be calculated.
Concept Introduction:
It is considered
This is an isothermal mixing process at constant pressure. Since no moving parts the system, so external work done is zero.
First law of
For isothermal process,
Therefore,
Integrating for overall process,
Here
Here
Rate of heat transfer,
(c)
Interpretation:
Rate of entropy generation (WK-1) should be calculated.
Concept Introduction:
Entropy of mixing can be calculated using following formula:
Here, n is number of moles, R is Universal gas constant and x is mole fraction.
