Orifice Sizing Pro

Professional engineering software for orifice plate sizing and flow calculations.

Orifice Sizing Pro is a powerful engineering application designed for process, mechanical, piping, and instrumentation engineers. It performs accurate calculations for designing and sizing restriction orifice plates used in gas and liquid flow systems.

The application calculates the relationship between flow rate, pressure loss, and orifice geometry as fluid passes through an orifice plate. Orifices are commonly used to restrict flow, reduce upstream pressure, or measure flow rate in industrial processes.

As fluid passes through the orifice opening, a pressure differential is created across the plate. While part of this pressure is recovered downstream, some pressure loss is permanent. The application assists engineers in selecting an appropriate orifice size while ensuring reliable and practical engineering design.

Key Features

• Calculate orifice diameter
