Calculate Heat Transfer Correction Factor



Formula

The formula to calculate the Heat Transfer Correction Factor (CF) is:

\[ CF = \frac{LMTD}{TMTD} \]

What is a Heat Transfer Correction Factor?

The heat transfer correction factor is a dimensionless number used in heat exchanger design to account for deviations from ideal counterflow or parallel flow conditions. It adjusts the log mean temperature difference (LMTD) to reflect the actual mean temperature difference (TMTD) in the heat exchanger. This factor is crucial for accurately determining the heat transfer rate and ensuring the heat exchanger operates efficiently under real-world conditions.

Example Calculation

Let's assume the following values:

Using the formula:

\[ CF = \frac{20}{15} = 1.33 \]

The Heat Transfer Correction Factor is approximately 1.33.
