, It can be a liquid or a gas
What are the differences between a liquid and a gas? - 🧠ANSWER ✔✔-
Gas is a fluid that will transmit power until pressure is equal, liquid is a fluid
that will transmit power irrespective of pressure
- Gas is compressible, liquids are virtually incompressible
- Liquids are used in hydraulic systems whereas gases are used in
pneumatic systems
The theory of hydraulics means what? - 🧠ANSWER ✔✔- A force acting on
a small area can create a much larger force by acting on a larger area by
virtue of hydrostatic pressure
- It also means that a large amount of energy can be carried by a small flow
of highly pressured fluid
What is hydrostatic pressure? - 🧠ANSWER ✔✔- The pressure exerted by a
fluid at equilibrium at a given point within the fluid, due to the force of
gravity
- Hydrostatic pressure increases in proportion to depth measured from the
surface because of the increasing weight of the fluid exerting a downward
force from above
