- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
Temperatures are absolute and the engine is an ideal reversible Carnot engine.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
