Piston Acceleration Calculator

Formula

The formula to calculate the Piston Acceleration is:

\[ PA = \left( \frac{RPM^2 \cdot S}{2.189} \right)^{11/3} \]

Where:

\(PA\) is the Piston Acceleration (ft/s²)
\(RPM\) is the rotations per minute
\(S\) is the stroke length (inches)

What is Piston Acceleration?

Piston Acceleration (PA) is a measure of the change in velocity of a piston within an engine, typically expressed in feet per second squared (ft/s²). It is calculated based on the RPM and stroke length of the piston.

Example Calculation

Let's assume the following values:

RPM = 3000
Stroke Length (S) = 4 inches

Using the formula:

\[ PA = \left( \frac{3000^2 \cdot 4}{2.189} \right)^{11/3} \approx 2.88 \times 10^{26} \, \text{ft/s²} \]

The Piston Acceleration is approximately \(2.88 \times 10^{26}\) ft/s².
