How can the specific gravity of a liquid or solid be expressed?
• As a ratio between the weight of the substance and the density of a volume of water
• As a ratio between the weight of the substance and the weight of an equal volume of
water

• pressure and temperature
• temperature and weight - ✔✔pressure and density
The study of hydraulics was originally confined to the study of the physical behavior of
water at rest and in motion. The term "hydraulics" now includes the physical behavior
of all
