A heat engine with an efficiency of 17 % does 836 J of work in each cycle. How much heat must be supplied from the high-temperature source in each cycle?
3 Answers
Explanation:
Coefficient of efficiency of a heat engine is defined as the ratio of work done
So,we can write,
Given,
So,
See below
Explanation:
Let's recall the definition of efficiency:
So, we are given the output of work here as
Let's substitute and solve:
The total energy consumed per cycle is 4918 J
Explanation:
17 % efficiency means that in one cycle,
Therefore if 836 J of work is done in each cycle, solving the following equation for
