Hulls are subject to various hydrostatic and hydrodynamic constraints. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. This prevents the existence of a hydrodynamic mechanism for angular momentum transport. These areas need to be lubricated by the fluid being pumped (hydrodynamic lubrication). The elution volume (Ve) decreases roughly linear with the logarithm of the molecular hydrodynamic volume. Rather, the fired projectile maintains its ballistic trajectory underwater by hydrodynamic effects. The VDS body is a streamlined fairing fitted with Y-shaped hydrodynamic vanes for towing stability. This minimizes the effect of hydrodynamic drag while underway, allowing for greater speed. This temperature is consistent with a hydrodynamic calculation that simulated the entire experiment. Acoustic focusing technology is used in some flow cytometers to support hydrodynamic focusing. GPC separates based on the size or hydrodynamic volume (radius of gyration) of the analytes. Fish rely on both vision and on hydrodynamic signals relayed through its lateral line. Instead they exhibit structures similar to hydrofoils in order to provide hydrodynamic lift. The TAM's transmission is a Renk HSWL-204 automatic, with a hydrodynamic torque converter. There is no possibility of achieving hydrodynamic bearing performance on normal sliding machine ways.
