5 Questions
Which force acts on a particle immersed in a liquid and has a direction opposite to the gravitational force?
Lifting force
What is the total force acting on a particle in a suspension, considering the gravitational force and the lifting force?
$F = F_g - F_p$
What is the mass of fluid expelled from the body when calculating the lifting force?
$m_s$
What is the equation for the magnitude of the total force acting on a particle in a suspension?
$F = (\rho - \rho_{sol})Vg$
What will be the direction of the velocity of a particle in a suspension when the density of the particle is greater than the density of the solvent?
