STEP 0: Pre-Calculation Summary

Formula Used

Thermal efficiency given Waste energy = 1-Waste Heat/Thermal Energy
η_th = 1-Q_out/Q_in
This formula uses 3 Variables

Variables Used

Thermal efficiency given Waste energy - Thermal efficiency given Waste energy is the percentage of heat energy that is transformed into work in a heat engine.
Waste Heat - (Measured in Joule) - Waste Heat is the amount of input heat energy that is not converted into work.
Thermal Energy - (Measured in Joule) - Thermal Energy is the input heat energy to a given system. This input heat energy is converted into useful work and a part of it is wasted in doing so.

STEP 1: Convert Input(s) to Base Unit

Waste Heat: 340 Joule --> 340 Joule No Conversion Required
Thermal Energy: 640 Joule --> 640 Joule No Conversion Required

STEP 2: Evaluate Formula
