FAQ
What is Orifice Flow used for?
Orifice Flow is used to quickly compute the flow rates of liquids and gases in pipes and conduits using orifice plates, a common method in industrial applications. It helps engineers and designers in analyzing and designing fluid flow systems.
What fluids does Orifice Flow support?
Orifice Flow supports fifteen of the most common industrial fluids, including Air, Steam, Water, Nitrogen, Oxygen, Hydrogen, Helium, CO2, Methane, Ethane, Chlorine, Ammonia, Argon, Hydraulic oil, and HFC(R410A). It also allows users to create and save custom fluid properties.
Can I use Orifice Flow for custom fluids?
Yes, Orifice Flow allows users to create custom fluid profiles by inputting their specific property data. These custom fluids can be saved for future use, making the app versatile for unique industrial needs.
What orifice types are supported by Orifice Flow?
Orifice Flow supports four different standard orifice designs, providing recommended discharge coefficients. The app's model is also valid for nozzles and venturi-flow meters where the discharge coefficient is unity.
Does Orifice Flow support different units of measurement?
Yes, users can choose between SI and USCS unit standards for both flow rate and pressure drop measurements. This flexibility ensures compatibility with various international and regional engineering practices.
How accurate is Orifice Flow?
The app's results are consistent with industry-standard methods, with differences typically less than 0.1% as demonstrated in a case study. Users can also edit the discharge coefficient using manufacturer's data for enhanced accuracy.
What devices is Orifice Flow available on?
Orifice Flow is available for iPhone and iPod devices. It was last updated on April 29, 2025, with version 2.2.
What is the price of Orifice Flow?
Orifice Flow is a paid application priced at $3.99. There are no in-app purchases or advertisements associated with this utility.
