This orifice plate pressure drop and flow calculation requires Java.

Pressure drop occurs with frictional forces, caused by the resistance to flow on a fluid as it flows through the tube or pipe.

The main factors of resistance to fluid flow are fluid viscosity and fluid velocity.

Pressure drop increases proportional to the frictional shear within the pipe.

High flow velocities and or high fluid viscosities result in a larger pressure drop across a section of pipe or a valve or elbow.

This particular pressure drop calculator deals with what happens with orifice plates.

Orifice plate pressure drop calculator is used for flow rate measuring in pipe systems.

With orifice plate, pressure drop is created.

Based on the magnitude of pressure drop, flow rate can be calculated.

The pressure drop calculation formula for the pipe is explained in more detail below.Practical for larger tube diameters and for dirty fluid where other methods are impractical.

It can be used as liquid, gas or air flow meter and the results can be checked against the textbook formula to gain confidence in using this easy to use orifice plate pressure drop flow rate calculation.

Fluid is considered as incompressible, so density (rho) and temperature (T) are constant through tube.

Also necessery coeffients: expansion - e and discharge - C are calculated and results are shown.
