Heat Engine Work Calculator
To find work done by a heat engine, subtract the heat rejected from the heat absorbed.
This calculator helps you find the work done by a heat engine. A heat engine takes in heat energy, uses some of it to do work, and then releases the remaining heat.
This tool is useful for students, engineers, and thermodynamics learners who study energy conversion, engine efficiency, and mechanical work. Instead of solving equations by hand, just enter the values, and the calculator will give the answer instantly.
Formula:
The formula for work done by a heat engine is:
| Symbol | Meaning |
|---|---|
| Whe | Work Done by Heat Engine (Joules) |
| Q1 | Heat Absorbed (Joules) |
| Q2 | Heat Rejected (Joules) |
What is Work Done by a Heat Engine?
A heat engine converts heat energy into work. It absorbs heat (Q1) from a hot source, does useful work (Whe), and releases leftover heat (Q2) into the surroundings.
For example, in a car engine, fuel burns to create heat, which powers the pistons and moves the vehicle forward. Some heat is lost through the exhaust and cooling system. This principle is used in cars, power plants, and refrigerators.
Understanding heat engine work helps in studying engine efficiency, thermodynamics, and energy systems.
Final Words:
To sum up, a heat engine converts heat into useful work. This calculator makes it quick and easy to find work done in physics and engineering problems.
FAQs:
1. How do you calculate work done by a heat engine?
Use the formula: Whe = Q1 – Q2, where Q1 is heat absorbed and Q2 is heat rejected.
2. How do you calculate engine heat rate?
The heat rate measures how efficiently an engine converts heat into work and is related to thermal efficiency.
3. What is the formula for heat work done?
Work done by a heat engine follows the equation Whe = Q1 – Q2.
