positive displacement pump
A hydraulic pump that uses an impeller or propeller to move fluid by momentum, as opposed to a positive displacement pump, which moves discrete quantities of fluid with each rotation. A typical application of a non-positive displacement pump is the coolant pump, or water pump, on a radiator-cooled engine.Read more: What_is_a_non-positive_displacement_pump
fluid
A siphon uses atmospheric pressure to move liquid over an obstacle. By creating a vacuum at the top of the siphon, atmospheric pressure pushes the liquid up and over the obstacle.
Hydraulic systems use liquid, typically oil, to transmit pressure in a confined fluid. This is achieved by applying force at one point within a fluid to create a pressure, which is then transmitted undiminished in all directions throughout the fluid to produce mechanical work at another point within the system.
A pitot tube uses Bernoulli's equation to measure fluid flow velocity by comparing the pressure difference between the stagnation point and the dynamic pressure of the fluid. This difference in pressure is used to calculate the velocity of the fluid flowing past the pitot tube.
diffusion using capillaries and tissue fluid
steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
When a student uses a straw to blow a stream of air between two papers, the difference in air pressure causes the papers to move apart. This is due to the Bernoulli principle, which states that as the speed of a fluid (in this case, air) increases, its pressure decreases. The faster-moving air between the papers creates lower pressure, leading to the papers separating.
A hydrostatic skeleton is a structure found in certain invertebrates like jellyfish and worms that uses fluid pressure to provide support and movement. It allows these organisms to maintain their body shape and move by altering the pressure of the fluid within their bodies.
Compression refrigeration uses a compressor to increase the pressure of the working fluid after the evaporator. Absorbtion refrigeration uses heat (usually waste heat from another process) to raise the pressure.
A hydraulic system uses pressure to create movement. Hydraulic systems operate by transmitting force through a fluid, usually oil, which is pressurized within a closed system and then used to move components like cylinders or motors. This technology is commonly used in applications like construction equipment, automotive brakes, and airplane flight controls.
Not really. It does have a hydro-skeleton where it uses pneumatic pressure to move along.
