STEP 0: Pre-Calculation Summary
Formula Used
Mean Piston Speed = 2*Stroke Length*Engine Speed
sp = 2*L*N
This formula uses 3 Variables
Variables Used
Mean Piston Speed - (Measured in Meter per Second) - Mean Piston Speed is the average speed of the piston over one engine revolution.
Stroke Length - (Measured in Meter) - Stroke length is the distance travelled by piston in cylinder from BDC to TDC or vice versa.
Engine Speed - (Measured in Radian per Second) - Engine Speed is the speed at which the crankshaft of the engine rotates.
STEP 1: Convert Input(s) to Base Unit
Stroke Length: 15 Centimeter --> 0.15 Meter (Check conversion here)
Engine Speed: 4000 Revolution per Minute --> 418.879020457308 Radian per Second (Check conversion here)

Mean piston speed Formula

Mean Piston Speed = 2*Stroke Length*Engine Speed
sp = 2*L*N

What is the purpose of mean piston speed?

The mean piston speed is the piston speed averaged over one engine revolution. A shorter stroke enables the engine to produce a higher rotating speed at a constant mean piston speed but also increases the speed at which the piston must travel in each revolution.

How to Calculate Mean piston speed?

Mean piston speed calculator uses Mean Piston Speed = 2*Stroke Length*Engine Speed to calculate the Mean Piston Speed, The Mean piston speed formula is defined as the distance traveled by a piston in a specified amount of time. Mean Piston Speed is denoted by sp symbol.

How to calculate Mean piston speed using this online calculator? To use this online calculator for Mean piston speed, enter Stroke Length (L) & Engine Speed (N) and hit the calculate button. Here is how the Mean piston speed calculation can be explained with given input values -> 125.6637 = 2*0.15*418.879020457308.
