Answer:
Explanation:
a) for shifting reactions,
Kps = ph2 pco2/pcoph20
=[h2] [co2]/[co] [h2o]
h2 + co2 + h2O + co + c3H8 = 1
it implies that
H2 + 0.09 + H2O + 0.08 + 0.05 = 1
solving the system of equation yields
H2 = 0.5308,
H2O = 0.2942
B) according to Le chatelain's principle for a slightly exothermic reaction, an increase in temperature favors the reverse reaction producing less hydrogen. As a result, concentration of hydrogen in the reformation decreases with an increasing temperature.
c) to calculate the maximum hydrogen yield , both reaction must be complete
C3H8 + 3H2O ⇒ 3CO + 7H2( REFORMING)
CO + H2O ⇒ CO2 + H2 ( SHIFTING)
C3H8 + 6H2O ⇒ 3CO2 + 10 H2 ( OVER ALL)
SO,
Maximum hydrogen yield
= 10mol h2/3 molco2 + 10molh2
= 0.77
⇒ 77%
Answer:
1. The net power developed=9370.773KW
2. Thermal Efficiency= 0.058
Explanation
Check attachment
In the case above, poor connection at the pressure cycling switch and also a faulty A/C clutch coil could be the cause.
<h3>What is likely the reason when an A/C compressor will not engage if A/C is turned on?</h3>
The cause that hinders the A/C Compressor from engaging are:
- Due to low pressure lockout.
- Due to a poor ground
- Due to bad clutch coil.
- Dur to an opening in the wire that links to the clutch coil.
- Due to a blown fuse.
Note that the pressure switches is known to be one that control the on/off function of any kind of AC compressor and as such, if there is switch failure, it can hinder the AC compressor from functioning at all.
Therefore, technician A and B are correct.
