WebFeb 2, 2011 · 140189. Drag coefficient is a dimensionless factor of proportionality between overall hydrodynamic force vector on a body in a liquid or gas flow and the product of reference area S of the body (commonly at midship section) and velocity head q. where , and v s are the velocity vectors of the fluid and the body, is the relative velocity of the ... Webpressure drag. The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag or air resistance. When the fluid is a liquid like water it is called hydrodynamic drag, but never "water resistance". Fluids are characterized by their ability to flow. carefree winter havenThe force between a fluid and a body, when there is relative motion, can only be transmitted by normal pressure and tangential friction stresses. So, for the whole body, the drag part of the force, which is in-line with the approaching fluid motion, is composed of frictional drag (viscous drag) and pressure drag (form drag). The total drag and component drag forces can be related as follows: brooks brothers red fleece store
