Motor VFD Drive features
Modern DC and AC motor drives provide features useful when using electric motors as final control elements. Some common features seen in both VSDs and VFDs are listed here: Speed…
AC Motor Braking
There are several different methods useful for causing an AC induction motor to brake, or slow down: DC injection Dynamic braking Regenerative braking Plugging DC injection uses the technique of…
Basics of Orifice Plates
Orifice plates are typically sandwiched between two flanges of a pipe joint, allowing for easy installation for fluid to flow through the pipe.
Square-root characteristics of Differential Pressure Flow Meters
Differential pressure developed by a venturi, orifice plate, pitot tube, or any other flow element is proportional to the square-root of flow rate.
Mass Flow Calculations
Measurements of mass flow are preferred over measurements of volumetric flow in process applications where mass balance is important.
Volumetric Flow Calculations
Volumetric Flow Calculations use differential pressure produced by any flow element tube with any particular fluid density at a specified flow rate.
Hydraulic Systems Objective Questions
Hydraulic Systems Objective Questions 1. Heavy lifting work is often accomplished by shifting fluids in big machines. The power system of such machines can be described as a) Reciprocating b)…
