What is the formula for calculating the efficiency of a heat engine?

Physics
1 answer:
Olegator [25]3 years ago
7 0

Explanation:

The efficiency of a heat engine is defined as the ratio of the work output to the heat input into the system.

  •   It is highly impossible to get an engine that is 100% efficient.
  • A heat engine that is 100% efficient suggests that all the heat input into the system is used to do work completely.
  • There is no heat loss.

      Efficiency = \frac{work output}{heat input} x 100

Efficiency has no unit
