Engine Displacement (cc) = (Bhp x 5000) / Max RPM
Where:
Bhp: Brake horsepower
Max RPM: Maximum revolutions per minute
Given:
Bhp = 33 bhp
To find:
Engine Displacement (cc)
Max RPM for most motorbikes is generally between 10,000 to 14,000 RPM. Let's assume an average Max RPM of 12,000 RPM for this calculation.
Engine Displacement (cc) = (33 bhp x 5000) / 12,000 RPM
Engine Displacement (cc) = (165,000) / 12,000
Engine Displacement (cc) ≈ 13.75 cc
Therefore, a 33 bhp motorbike would have an engine displacement of approximately 13.75 cubic centimeters (cc).
