Intercooler Efficiency Calculator

Formula

To calculate the Intercooler Efficiency (\(E_{int}\)):

\[ E_{int} = \left( \frac{T_{pre} - T_{post}}{T_{pre} - T_{amb}} \right) \times 100 \]

Where:

\(E_{int}\) is the Intercooler Efficiency (%)
\(T_{pre}\) is the pre-intercooler temperature (°C)
\(T_{post}\) is the post-intercooler temperature (°C)
\(T_{amb}\) is the ambient temperature (°C)

Intercooler Efficiency Definition

Intercooler efficiency is a measure of how effectively an intercooler reduces the temperature of the air passing through it. It is expressed as a percentage, calculated by comparing the temperature drop across the intercooler to the difference between the pre-intercooler temperature and the ambient temperature.

Example Calculation 1

Let's assume the following values:

Pre-Intercooler Temperature (\(T_{pre}\)) = 150°C
Post-Intercooler Temperature (\(T_{post}\)) = 50°C
Ambient Temperature (\(T_{amb}\)) = 25°C

Using the formula:

\[ E_{int} = \left( \frac{150 - 50}{150 - 25} \right) \times 100 = \left( \frac{100}{125} \right) \times 100 = 80\% \]

The intercooler efficiency is 80%.

Example Calculation 2

Let's assume the following values:

Pre-Intercooler Temperature (\(T_{pre}\)) = 200°C
Post-Intercooler Temperature (\(T_{post}\)) = 70°C
Ambient Temperature (\(T_{amb}\)) = 30°C

Using the formula:

\[ E_{int} = \left( \frac{200 - 70}{200 - 30} \right) \times 100 = \left( \frac{130}{170} \right) \times 100 \approx 76.47\% \]

The intercooler efficiency is approximately 76.47%.
