Developer's DescriptionBy NorCraftCalculate size, flowrate, or pressure drop for gas and liquid orifices.Program ISO-5167 will size orifice plates for given design conditions, find pressure drop for a given flow, or flow for a given pressure drop. The ISO-5167-2: 2003 standard is originally designed for gas orifices. In this programs the standard is also used for liquid orifices. The program lets you calculate the following orifice-types: 1) Gas Orifice; 2) Liquid Orifice; 3) Restriction Orifice - Gas; 4) Restriction Orifice - Liquid.The program can be used to calculate size, flowrate or pressure drop of the following fluids:Gases: 1) Natural gas; 2) Nitrogen; 3) Air.Liquids: 1) Oil; 2) Water; 3) Methanol/Water mixtures; 4) Monoethylene glycol/Water mixtures; 5) Ethylene glycol/Water mixtures; 6) - Triethylene glycol/Water mixtures.
