Difference between laminar and turbulent flow?

What is the difference between laminar and turbulent flow? The film of fluid that touches the container does not move because of friction with the container’s surface. But the fluid in the middle of the stream does. In laminar flow the transition from not moving to full-speed motion is continuous. Each thin film of water […]

Difference between hydraulics & pneumatics?

Hydraulics deals with the use of liquid in motion, usually in a device such as a machine. Oil is the most common liquid used in pumps, lifts, and shock absorbers. Whereas hydraulics uses liquids to achieve mechanical advantage, pneumatics uses compressed gas. Since gases can be compressed and stored under pressure, releasing compressed air can […]
