Efficiency of Heat Engine Solution

STEP 0: Pre-Calculation Summary

Formula Used

Efficiency of Heat Engine = (Heat Input/Heat Output)*100
η_HE = (Q_in/Q_out)*100
This formula uses 3 Variables

Variables Used

Efficiency of Heat Engine - Efficiency of Heat Engine is defined as the ratio of work done by the heat engine to heat absorbed per cycle.
Heat Input - (Measured in Joule) - Heat Input is the amount of energy transferred during work to the system.
Heat Output - (Measured in Joule) - Heat Output is the amount of energy transferred during work from the system.

STEP 1: Convert Input(s) to Base Unit

Heat Input: 400 Joule --> 400 Joule No Conversion Required
Heat Output: 300 Joule --> 300 Joule No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_HE = (Q_in/Q_out)*100 --> (400/300)*100

Evaluating ... ...

What is the best heating efficiency?

While natural gas is only relevant to gas boiler running costs, electricity applies to both heat pumps and electric boilers. However, heat pumps generally offer 250-350% efficiency, making them far cheaper to run than electric boilers which provide about 99-100% efficiency.

How to Calculate Efficiency of Heat Engine?

Efficiency of Heat Engine calculator uses Efficiency of Heat Engine = (Heat Input/Heat Output)*100 to calculate the Efficiency of Heat Engine, Efficiency of Heat Engine is defined as the ratio of work done by the heat engine to heat absorbed per cycle. Electric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat. Efficiency of Heat Engine is denoted by η_HE symbol.
