Answer:
The preliminary work breakdown structure will be divided into two steps, the first is to draw the first level and the second is to draw the second level.
Explanation:
Please look at attachment.
A binary mixture of benzene(1) and toluene(2) is flashed to 75 kPa and 90°C. Analysis of the effluent liquid and vapor streams f
reom the separator yields: x1 = 0.1604 and y1 = 0.2919.
An operator remarks that the product streams are "off-spec", and you are asked to diagnose the problem.
(a) Verify that the exiting streams are not in binary equilibrium.
(b) Verify that an air leak into the separator could be the cause.

Answer:
A)
B)
C) Second law efficiency 4.85%
exergy destruction for the cycle = 9.3237 kW
Explanation:
Given data:
degree celcius
degree celcius
Power to refrigerator = 9.8 kW
Cp = 3.35 kJ/kg degree C
b)
wil be max when COP maximum
taking surrounding temperature T_H = 20 degree celcius
we know that
c) second law efficiency
exergy destruction os given as
= 9.8 - 0.473 = 9.3237 kW
