A car V8 has a bore of 4 in. and a stroke of 2.5 in., what is the engine size?
To calculate the engine size of a V8 car, you will need to use the formula:
Engine Size = (Bore²) × Stroke × Number of Cylinders × 0.7854
In this case, for a V8 car with a bore of 4 in. and a stroke of 2.5 in., the number of cylinders is 8.
Using the formula, we can calculate the engine size:
Engine Size = (4²) × 2.5 × 8 × 0.7854
= 64 × 2.5 × 8 × 0.7854
= 100.5312 in³
Therefore, the engine size of the V8 car is approximately 100.5312 cubic inches.
