Buoyancy formula In f-float = g-row = pgv-row, if an object floats or floats, then buoyancy is the gravity of the object. In this case, does g-row refer to the gravity of the object or the gravity of some objects immersed in water? Are the two equal?

G row is precisely the gravity of the liquid, not the weight of the object immersed in the liquid, because there is a difference in density between the two
Let the density of the object be ρ and the volume be v
① In floating condition:
G row = ρ liquid GV row
V-discharge refers to the volume of liquid discharged, at which time v discharges ρ liquid
