Torsional Stiffness

Torsional stiffness is the measure of how much radial torque force an object can withstand, or has the ability to experience without deforming. This is a central principal to both civil and mechanical engineering, and plays a key component when designing and testing structural parts or tools. Anything that is subjected to a rotational force …

What is a Laminar Flow Wing?

One of the most important design aspects in the realm of human flight is making sure the drag experienced by a wing is limited enough to get off the ground, and efficient enough not to burn so much fuel that the cost is not worth the flight. The best way to ensure these requirements are …

Compared: SDR 26 vs. SDR 35

SDR 26 and SDR 35 are size classifications of PVC pipe. The SDR, or standard dimensional ratio, is the ratio between a pipe’s outer diameter and its minimum wall thickness. As the SDR rating increases, the pipe wall becomes thinner relative to the outer diameter. That means that PVC pipes with lower SDR ratings are …

Advantages of Turbulent Flow

Flow of fluids, both gaseous and liquid, is generally categorized into two distinct groups: laminar and turbulent. While one might assume that turbulent flow means “faster”, the truth is actually a little more complicated than that. Understanding whether a flow is turbulent and how it behaves is fundamental to the study of aerodynamics and plays …

Why Does Flow Become Turbulent?

Fluid dynamics – and more specifically, fluid flow – is the study of how fluids (both liquid and gas) move when subjected to unbalanced forces. Flow can either be laminar or turbulent. Laminar flow occurs when fluid particles are moving together in the same direction in parallel paths. It’s defined as smooth, steady motion where …
