Damping constant of water

WebThe critical damping coefficient of a system is a function of its mass (m), natural frequency (ω n ), and stiffness (k) as the following equations depict. But measuring the actual damping requires empirical methods that vary … WebThe damping force is proportional to the velocity of the mass, and it adds a term to the equation of motion for the mass-spring system, which is now. m ( d2x / dt2) + c ( dx / dt) + kx = 0. The characteristic equation that corresponds to this is mr2 + cr + k = 0. The roots to this equation are [- c ±√ ( c2 - 4 mk )]/2 m.
