  • Rheology of Crude Oil at High Pressure
    . and stick to pipe walls or form sludge at the. bottom of a storage tank, even in warm climates. This wax deposition can block flow lines, reduce. throughput, clog pumps, and inhibit the performance. of metering devices that measure transferred. crude oil. The pressure required to start the flow
  • Torque Sensor Application - Constant Flow Pump
    In the constant flow pump, a stepping / stepper motor is used to create a pumping function and allow fluid to flow. A reaction torque sensor attached to the back end of the motor monitors the required torque and can relate the changes in torque to the flow rate or alarm the operator when the torque
  • Water Aspirators: Cheap Pumps With Environmental Impact & High Operating Costs
    Water aspirators are a common way of creating a low strength vacuum for many standard laboratory applications. Their simple design employs water running through a narrowing tube to create a reduced pressure via the Venturi effect. The pump's performance is dependent upon the temperature
  • Designing Atmospheric-Pressure Plasma Sources for Surface Engineering of Nanomaterials
    field,. greatly improving the device throughput. In addition, the. DC field creates electrokinetic flow across the length of the. sample channel, alleviating the need for a pump in pressure-driven. flow [18, 20-28]. Contactless dielectrophoresis (cDEP) is a promising new. DEP technique [29
  • MSilica Nanoparticles Treated by Cold Atmospheric-Pressure Plasmas Improve the Dielectric Performance of Organic-Inorganic Nanocomposites
    Microfluidic mixing using contactless dielectrophoresis. The first experimental evidence of mixing enhancement in a microfluidic system using. contactless dielectrophoresis (cDEP) is presented in this work. Pressure-driven flow of. deionized water containing 0.5 mm beads was mixed in various
  • Interphex Preview, Part Deux
    by utilizing a swinging motion instead of the customary rotating motion. It provides a hermetically sealed environment no rotating shaft seal and is ideal for low-shear, high-purity mixing applications. Components for High Purity Fluid Handling Process Flow Technologies (CPFT) specializes
  • How to Choose the Right Size Air Release Valve
    during the filling or draining of a piping system. Air comes out of solution in a pipeline because of low-pressure zones created by partially open valves, variations in flow velocity and changes in pipeline system elevation. An air pocket in system high points may reduce the flow of water
  • Derating For Real World Conditions
    . Resistivity is a measure of how strongly a material opposes the flow of electric current. A low resistivity material, such as silver, readily allows the flow of current in an. electrical circuit. A material with higher resistance, such as nickel, impedes the flow of. current in the circuit
