- That is, liquids flow (so they are a type of fluid), with the molecules held together by mutual attraction. When a liquid is placed in a container with no lid, it remains in the container. Because the atoms are closely packed, liquids, like solids, resist compression; an extremely large force is necessary to change the volume of a liquid.

Gases are easy to squash: everyone knows how easyit is to squeeze a balloon. Solids are just the opposite.If you've ever tried squeezing a block of metal or a lump ofwood, with nothing but your fingers,you'll know it's pretty much impossible. But what about liquids?Where do they fit in? You probably know that liquids are anin-between state, a bit l...
Turn a water pistol on its end and this is(crudely simplified) what's going on inside: Photo: A simplified view of a hydraulic waterpistol. When you press on the trigger (shown in red), you apply a relativelylarge force that moves the trigger a short distance. Because the water won'tsqueeze into a smaller space, it gets forced through the body of t...
You can see hydraulics at work in this digger.When the driver pulls a handle, the digger's engine pumpsfluid intothe narrow pipes and cables (shown in blue), forcing the hydraulic rams (shownin red) to extend. The rams look a bit like bicycle pumps working inreverse. If you put several rams together, you can make a digger'sarm extend and move much ...
How do hydraulic parts work together? Just like the components (parts) in something electric or electronic, they're connected into circuits. Instead of electrons whizzing around, there's hydraulic fluid flowing instead.A hydraulic circuit contains (at a minimum) something that supplies hydraulic power (a tank of fluid and apump—similar to the batte...
Not all hydraulic machines are so obvious, however; sometimes their hydraulic rams are hidden out of sight. Elevators("lifts") keep their workings well hidden, so it's not always apparent whether they're working in the traditional way (pulled up and down by a cable attached to a motor) or using hydraulics instead. Smaller elevators often use simple...
Dec 3, 2020 · Gender fluidity refers to change over time in a person’s gender expression or gender identity, or both. That change might be in expression, but not identity, or in identity, but not expression. Or both expression and identity might change together.

Fluid mechanics, science concerned with the response of fluids to forces exerted upon them. It is a branch of classical physics with applications of great importance in hydraulic and aeronautical engineering, chemical engineering, meteorology, and zoology.
A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids. Density is the mass per unit volume of a …
In this section we modify the fluid system to allow for flow. The flow is steady-state which means it is constant over time for a given fluid system. To describe flow, kinetic energy-density, in …
Oct 5, 2020 · Fluid dynamics isn’t the least complicated thing in the world, so we’ll stick to the basics for this article. Any given fluid can flow in either a steady-state or the fluid can be turbulent.
