Archimedes' principle (or Archimedes's principle) is a law of physics stating that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces. In other words, an immersed object is buoyed up by a force equal to the weight of the fluid it actually displaces. Archimedes' principle is an important and underlying concept in the field of fluid mechanics. This principle is named after its discoverer

1. Archemides Principle:
By Dr. Robert D. Craig, Ph.D.

2. Archemides Principle:
• Archemides Principle:
• The weight of the displaced fluid is directly
proportional to the volume of the displaced
fluid (specifically if the surrounding fluid is of
uniform density). Thus, among objects with
equal masses, the one with greater volume
has greater buoyancy.

4. . Specific gravity
• Archimedes' principle, or the law of
upthrust, is:
• "a body immersed in a fluid is buoyed up by a
force equal to the weight of the displaced
fluid."

• Opening a blocked heart artery with a balloon
and then propping it open with a wire-mesh
stent has become a near-equal partner with
bypass surgery for restoring blood flow to the

11. Specific gravity
• Specific gravity is the ratio of the density
(mass of a unit volume) of a substance to the
density (mass of the same unit volume) of a
reference substance. Apparent specific gravity
is the ratio of the weight of a volume of the
substance to the weight of an equal volume of
the reference substance.

12. Specific gravity
• The reference substance is nearly always
water for liquids or air for gases. Temperature
and pressure must be specified for both the
sample and the reference

13. Specific gravity

14. Specific gravity
• where is the density of the sample and is the
density of water.
• The apparent specific gravity is simply the
ratio of the weights of equal volumes of
sample and water in air:
