Coeff of viscosity dimensional formula

Webrock mechanics. In rock: Stress-strain relationships. The coefficient of viscosity (η) is the ratio of applied stress to the rate of straining (change of strain with time). It is measured in units of poise; one poise equals one dyne-second per square centimetre. Read More. WebThe drag coefficient is generally given by the formula. CD= 2F D / ρv 2A. Where; ρ is the density of the cylinder, FD is the drag force, v is the velocity of the cylinder moving in the fluid, and A is the area of the cylinder. The area of the cylinder is given by. A=2πrh+2πr 2.
