(or gas) flows around a stationary body or, vice versa, if a body moves through a stationary medium, the hydrodynamic drag is the projection of the vector sum of all forces acting on the body onto the direction of motion. The hydrodynamic drag is X = cx(ρv2/2)S, where ρ is the...
accurate to 3-5 ml/min, the precision of Control board had two kinds, one kind is can not be adjusted, fixed flow; One with potentiometer, can adjust flow, thus realize the steamtodragthefunction of a shifting gear, etc. Greatly simplifies the customerinthedevelopment of steamtodragthe...
Miniaturized rotors based on Marangoni effect have attracted great attentions due to their promising applications in propulsion and power generation. Despite intensive studies, the development of Marangoni rotors with high rotation output and fuel econom
to-second gear shift, and how quickly you’re shifting, how properly you’re shifting, and the correct RPM you’re shifting at will affect your time. The 330’ and the 660’ are the middle-of-the-track guide that allow you to improve on shifting between first-to-second, and second-...
Unsure as yet for the final travel plans but most probable we will head out Harwich to Hook then up to Kiel in Germany and catch the 22-hour ferry to Oslo. We're hoping to catch Gardermoen Raceway in Norway the first week in June and then onto the four-day event at Tierp then ...
