Answer:
Explanation:
given data:
maximum temperature = 727 degree C =727 +273 = 1000 K
Minimum temperature = 27 degree C = 27 +273 = 300 K
Maximum efficiency is given as 
plugging all value from the above to get maximum efficiency
Answer:
A
Explanation:
Incase you need to re-read or you need to refresh your memory.
Also, Incase something happens, you will have the rules and guidelines.
Primitive transportation and storage systems that make local distribution ineffective if not impossible, and the lack of clean water and the lack of effective sewer systems are all examples of the barrier called physical & environmental barriers.
<h3>
What are the problems with having physical & environmental barriers?</h3>
Time, Place, Space, Climate, and Noise are the key environmental/physical constraints. Some are simple to change, while others may prove to be difficult.
Physical barriers are essentially defined by three primary factors: environment, distance, and medium unawareness. Environmental barriers, on the other hand, are connected to variables that occur in the current environment.

Answer:
Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 20 o C and exits at 5.0 bar. The refrigerant undergoes a throttling process. Determine the temperature, in o C, and the quality of the refrigerant at the exit of the expansion valve.
