Description
Label the hotter side and a declared hot-to-cold transfer sign.
Physical quantities require compatible units, coordinate directions, reference origins and model assumptions. Mass and weight, angular and cyclic frequency, particle velocity and wave speed are distinct quantities. Ideal single-axis, linear-spring and constant-torque terms describe supplied models rather than identify real material behavior or safe operating limits.
Label the hotter side and a declared hot-to-cold transfer sign.
When to use this tool
Use Heat Flow Sign Hot Cold Label when you already have temperatureA, temperatureB, positiveMeansAToB and need to label the hotter side and a declared hot-to-cold transfer sign.
How to use the tool and how it works
- Enter temperatureA, temperatureB, positiveMeansAToB. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read hotterSide, hotToColdSign. Use the output convention below.
Compare temperatureA/B; return hotterSide A, B or equal. Use the positiveMeansAToB switch to map the hotter-to-colder direction to +1/-1, or zero at equality.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| temperatureA | Temperature A | Required. Finite number. |
| temperatureB | Temperature B | Required. Finite number. |
| positiveMeansAToB | Positive Means ATo B | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| hotterSide | Hotter Side | Required. Text; maximum UTF-16 length 8192. |
| hotToColdSign | Hot To Cold Sign | Required. Safe integer. |

}Limitations and assumptions
- Temperatures must be comparable; this labels a direction without calculating heat flux, conductivity or actual thermal balance.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the full force, energy or wave model with compatible reference frames and units for a physical prediction. Include changing loads, material behavior and losses when the ideal constant-parameter term no longer represents the system.
