Ship velocity
http://www.navweaps.com/index_tech/tech-022.php Webv = ship velocity. u = exhaust velocity. M = ship mass, not including the working mass. m = total mass ejected from the ship (working mass). The term working mass is used primarily in the aerospace field. In more "down to earth" examples the working mass is typically provided by the Earth, which contains so much momentum in comparison to most ...
Ship velocity

WebThe wake has three parts: the velocity of the water around the hull; the boundary layer between the water dragged by the hull and the surrounding flow; and the waves created by the movement of the ship. The first two parts will reduce the velocity of water into the propeller, the third will either increase or decrease the velocity depending on ... Web2 Apr 2014 · Issue: When looking at the readings from VELOCITY:SURFACE:Z, they seem to be somehow mixed with VELOCITY:SURFACE:X. Upwards velocity seems to induce an 'Eastward' bias in the Z vector, with downwards velocities giving a 'Westward' bias. ...
