The Resistance Coefficient is used in a form of the Darcy Equation below: h L = hydraulic energy lost (head loss) from the fluid due to friction, in ftHow is the resistance coefficient method used to describe pressure loss?
The resistance coefficient method (or K-method, or Excess head method) allows the user to describe the pressure loss through an elbow or a fitting by a dimensionless number – K. This dimensionless number (K) can be incorporated into the Darcy-Weisbach equation in a very similar way to the equivalent length method.What is the coefficient of resistance per degree Celsius?
This is why figures of specific resistance are always specified at a standard temperature (usually 20o or 25o Celsius). The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α).What do you mean by negative coefficient of resistance?
Coefficients approaching zero can be obtained by alloying certain metals. • A negative coefficient for a material means that its resistance decreases with an increase in temperature. Semiconductor materials (carbon, silicon, germanium) typically have negative temperature coefficients of resistance.
