Problem 10.008 si refrigerant 22 enters the compressor of an ideal vapor-compression refrigeration system as saturated vapor at -40°c with a volumetric flow rate of 10 m3/min. the refrigerant leaves the condenser at 19°c, 9 bar. determine: (a) the magnitude of the compressor power, in kw. (b) the refrigerating capacity, in tons. (c) the coefficient of performance. (d) the rate of entropy production for the cycle, in kw/k.

answer:

constructing a building's framework requires a solid foundation

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
