Answer:

[tex]Q_{L}[/tex]= 41.66 KW

Explanation:

In a refrigerator COP = [tex]\frac{Q_{L} }{W_{In} } =\frac{T_{L} }{T_{H}-T_{L}  }[/tex]

where [tex]Q_{L}[/tex]= desired cooling effect

[tex]W_{in}[/tex]= work input= 10 KW

[tex]T_{L}[/tex]= 250 K

[tex]T_{H}[/tex]= 310 K

putting the values

[tex]\frac{Q_{L} }{W_{In} } =\frac{250}{310-250}[/tex]

[tex]Q_{L}[/tex]= 41.66 KW
