ANSWER:Solution 86P
Step 1 of 3
Here we need to calculate the heat transfer of energy into the system and Net work output
using the given coefficient of performance and heat transfer of energy out of system for a refrigeration cycle.
Given data,
Heat transfer of energy out of system,
Coefficient of performance,
To find,
Net work output,
Heat transfer of energy into the system,
