Answer:
Explanation:
60000 kJ / h = 60000 x 1000 / (60 x 60 )
= 16667 J /s
a)

where
and
are heat supplied and heat given from outside source .
Here
= 16667 J/s

= 15.684

16667 / W = 15.684
W= minimum power supplied = 1062.7 W.
b )
If 

=19.87



= 838.8 W .
Answer: well you get it for energy i think right
