Bananas are to be cooled from 28°c to 12°c at a rate of 1140 kg/h by a refrigerator that operates on a vapor-compression refrigeration cycle. the power input to the refrigerator is 9.8 kw. determine (a) the rate of heat absorbed from the bananas, in kj/h, and the cop, (b) the minimum power input to the refrigerator, and (c) the second-law efficiency and the exergy destruction for the cycle. the specific heat of bananas above freezing is 3.35 kj/kg·°c.

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

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
