Vacuum pressure describes a pressure lower than local atmospheric pressure, expressed either as a negative gauge pressure or as an absolute pressure above zero.
Mechanical EngineeringValidation is the process of confirming that a model, product, process, or system is suitable for its intended use in its intended context.
Industrial and Management EngineeringValve coefficient is a flow-capacity rating that relates valve opening, pressure drop, fluid properties, and flow rate under defined reference conditions.
Chemical EngineeringVapor pressure is the equilibrium pressure of a vapor in contact with its liquid or solid phase at a specified temperature.
Chemical EngineeringVector control is a motor-control method that transforms measured phase quantities into rotating reference-frame components so flux-producing and torque-producing currents can be controlled independently.
Electrical EngineeringA Venturi meter is a differential-pressure flowmeter that estimates flow rate from the pressure drop caused by accelerating fluid through a converging throat.
Mechanical EngineeringVibration isolation is the reduction of vibration transmission between a source and a receiver by using compliant, damping, inertial, or active elements.
Mechanical EngineeringViscosity is a measure of a fluid's resistance to shear deformation and relative motion between adjacent layers.
Mechanical EngineeringA voltage regulator is a circuit or device that keeps an output voltage within specified limits despite changes in input voltage, load current, and temperature.
Electronic EngineeringVolumetric efficiency is the ratio of the actual mass (or volume at reference conditions) of fluid inducted or discharged by a reciprocating machine per cycle to the mass (or volume) that would be inducted or discharged if the displacement volume were perfectly filled at inlet conditions.
Mechanical EngineeringThe von Mises criterion is a yield criterion that predicts that a ductile material begins to yield when the von Mises equivalent stress — a scalar measure of the distortional energy in the stress state — reaches the material's uniaxial yield strength.
Mechanical EngineeringVortex shedding is the periodic formation and release of alternating vortices behind a bluff body in a fluid flow.
