Heat Engine Work Calculator

How to Use the Calculator

1. Enter the heat input (Q_H) in joules (J). This is the amount of heat absorbed from the high-temperature reservoir.
2. Enter the heat rejected (Q_C) in joules (J). This is the amount of heat expelled to the low-temperature reservoir.
3. Click the "Calculate" button to compute the work done by the engine.
4. The result will be displayed in joules (J).

Working Principle

A heat engine is a device that converts thermal energy into mechanical work. The work done by a heat engine is given by the difference between the heat input and the heat rejected:

W = Q_H - Q_C

Where:

• W is the work done by the engine
• Q_H is the heat input from the high-temperature reservoir
• Q_C is the heat rejected to the low-temperature reservoir

This formula is derived from the first law of thermodynamics, which states that the energy input to a system must equal the energy output plus the change in internal energy of the system.
