The property of materials resistance to flow
WebbResistance is proportional to how much pressure is required to achieve a given flow, while conductance is proportional to how much flow occurs for a given pressure. Conductance and resistance are reciprocals. The resistance of an object depends on its shape and the material of which it is composed. Webb21 dec. 2024 · Properties Measured. Flow Function; a measure of the internal resistance to flow of a powder causing blockage (usually an arch or a rat-hole) in a hopper or feeder. Time Consolidation Flow Function; similar to the Flow Function, but with an understanding of how storing the powder for a period of time can lead to poor powder flow when …

Webb13 juni 2024 · Nominal resistance is the resistance of sensing element at 0 °C. For example, in pt100 RTD, the nominal resistance is 100 Ohm at 0 °C and the material is platinum. TCR is the change in resistance with per unit change in temperature. This value should be as high as possible. Platinum has TCR equal to 0.00392. WebbInsulators: Materials that present high resistance and restrict the flow of electrons. Examples: Rubber, paper, glass, wood and plastic. The higher the resistance, the lower the current flow. If abnormally high, one possible cause (among many) could be damaged conductors due to burning or corrosion.
