Pascal’s Law

No Comments

Pascal’s Law Pascal’s Law It states that the increase in pressure at one point of the enclosed liquid in equilibrium of rest is transmitted equally without loss to all other points of the liquid and also to the walls of the container, provided the effect of gravity is neglected. Proof. Let us consider that an…

Relative Density | Specific Gravity

No Comments

Relative Density | Specific Gravity Relative Density Relative density(R.D.) is defined as the ratio of the density of a given substance to the density of pure water at 4°C. R.D. = density of a given substance/density of pure water at 4°C R.D. is a unitless and dimensionless positive scalar physical quantity. Being a dimensionless/unitless quantity…
