Thermodynamic Cycles- Principles, Purpose, and Types
Thermodynamic cycles are processes that involve heat and work flowing into and out of a system. These systems usually intake a working fluid and output mechanical work or energy. These…

Graham GarciaHydraulic Diameter
Hydraulic diameter, DH, is the characteristic length used to determine Reynolds number when dealing with flow in non-circular mediums. Reynolds number may then be of use in determining whether a…
Stebin SamuelModulus of Rigidity – Equation, Steel Selection, and Values
The modulus of rigidity is the ratio of shear stress to shear strain. Thus, it measures the ability of the material to withstand distortion. However, the rigidity of the material…
DBTT – Ductile Brittle Transition Temperature
The ductile-brittle transition temperature, often referred to as DBTT, is the temperature at which there is a pronounced decrease in a material’s ability to absorb force without fracturing. At this…
Michael SattiStagnation Pressure – Uses and Real Life Applications
Stagnation pressure is the fluid pressure that is measured while an initially flowing fluid is fully at rest. The fluid still holds mechanical energy through pressure despite having no movement….
Shot Peening – Process, Machines, Applications, and Advantages
Shot peening is a mechanical treatment process in which the surface of a metal object is subject to a stream of very high velocity small spherical balls of metal, glass,…
Prandtl Number – Calculation and Effective Use
The Prandtl Number is an unitless ratio that describes the momentum diffusivity to thermal diffusivity of a liquid. Using a Prandtl number provides the relation of the thickness of the…
Reflectivity
Reflectivity is the property by which an object is able to reflect light or radiation. Optically speaking, it refers to the amount of light that is reflected from incident light…
Material Hardness
There are different ways to define hardness depending on the material. For minerals, it is the property of resistance of a material to scratching by another material. Metallurgy defines hardness…
Graphene
The thinnest material known to man, graphene provides extreme strength, thermal conductivity, and electrical conductivity on par with copper. As such, this material has made an uproar with the scientific…
