Carnot Cycle Efficiency Calculator
Calculate maximum thermal efficiency of a Carnot engine using hot and cold reservoir temperatures. Step-by-step solutions for ideal thermodynamic cycles.
Carnot cycle efficiency calculator:
This Carnot Cycle Efficiency Calculator is used to find the maximum thermal efficiency of a heat engine that works between a hot and cold reservoir. Input T H and T C to find efficiency, work output, and the input of heat using step-by-step solutions.
Carnot cycle efficiency Tool Formula:
The Carnot Cycle Efficiency Calculator assists engineers, students and researchers to calculate the maximum possible efficiency of an ideal heat engine working between two reservoirs. The Carnot cycle is a reversible thermodynamic cycle and its efficiency is only based on the temperature of the hot (T H) and cold (T C) reservoirs.
One can type T H and T C in Kelvin or Celsius. Maximum thermal efficiency η, work output, and heat input are calculated by the Carnot formulas with the help of the calculator:
\[ \textrm{Efficiency } (\eta) = 1 - \frac{Tc}{Th} \]
(where Tc = cold reservoir temperature, Th = hot reservoir temperature)
The solutions in steps demonstrate the change of efficiency with the difference of temperatures, and thus it is not very difficult to comprehend the limit of energy conversion in engines, turbines, and refrigeration cycles. This tool can best suit mechanical engineers, thermal engineers and students to ensure that they analyze the energy accurately and ascertain the maximum performance of ideal reversible engines. SI units are supported: K, °C, J, kJ.
