displacement volume

Notice that speed has dropped out of the equation and the only variables are the torque and displacement volume.

Displacement volume, which was calculated from the cylinder diameter, stroke and number of cylinders being the dimensions that determined the power for road taxation purposes.

By dividing the trunk into sections and applying geometric solids, principally conoid, paraboloid, and neiloid forms, trunk volume can be measured to within 5.0% of the water displacement volume.

Most other ways to estimate body fatness, such as by skin folds, body girths, body impedance, air displacement volume and body scanners are based on equations which predict body density, and are inaccurate.

It also allows for a design that greatly reduce water resistance (the part that generates waves) by moving as much displacement volume as possible to the lower hull and narrowing the waterline cross-section sharply, creating the distinctive pair of bulbous hulls below the waterline and the narrow struts supporting the upper hull.
