Relationship diagram between fluid machinery and energy storage

Are fluid systems mechanical systems?

Fluid systems are mechanical systems, since they obey Newton’s laws. They store energy as kinetic energy (energy of motion) or strain energy (energy of elastic deformation). Kinetic energy is dissipated as heat through viscous friction, which is lost from the system.

Why are fluids used in machine design?

Fluids, both liquids and gases, are used in machine design to transmit power, store energy, and actuate mechanisms. Fluids have mass and are compressible. Thus, they store both kinetic and strain energy. Further, fluids are generally confined within containers such as tubes, pipes, tanks, and cylinders.

What is a fluid machine?

A fluid machine is a device that converts energy between a fluid and mechanical energy. It transforms potential, kinetic, and intermolecular energy stored in a fluid into mechanical energy, usually transmitted by a rotating shaft.

What forms of energy does a fluid mass store?

A fluid machine is a device which converts the energy stored by a fluid into mechanical energy or vice versa. The energy stored by a fluid mass appears in the form of potential, kinetic and intermolecular energy. The mechanical energy, on the other hand, is usually transmitted by a rotating shaft.

What is the difference between mechanical energy and fluid energy?

The energy stored by a fluid mass appears in the form of potential, kinetic, and intermolecular energy. On the other hand, mechanical energy is usually transmitted by a rotating shaft. Machines using liquid, mainly water, are termed as hydraulic machines.

How do fluids store energy?

Fluids have mass and are compressible. Thus, they store both kinetic and strain energy. Further, fluids are generally confined within containers such as tubes, pipes, tanks, and cylinders. An additional mode of energy storage is the work that is done by those forces, which are exerted by fluids on their containers.
