The formula to calculate the Boost Pressure Ratio (BPR) is:
\[ \text{BPR} = \frac{B}{P} \]
Where:
The Boost Pressure Ratio (BPR) is a measure of the increase in pressure provided by a turbocharger or supercharger. It is calculated by dividing the total boost delivered by the total system pressure. This ratio helps in understanding the efficiency and performance of the boosting system.
Let's assume the following values:
Using the formula:
\[ \text{BPR} = \frac{30}{15} = 2 \]
The Boost Pressure Ratio is 2.
Let's assume the following values:
Using the formula:
\[ \text{BPR} = \frac{25}{10} = 2.5 \]
The Boost Pressure Ratio is 2.5.
