Determine orifice diameter

Evaluating and designing orifice plates is a key process in flow systems, commonly used to measure flow rate or regulate pressure in pipelines. Orifice plates act as a flow restriction, creating a pressure drop that can be used to calculate flow or control head loss. The precise design of these plates ensures proper system performance and efficiency.

This method calculates head loss based on the provided geometric parameters and flow rate. Head loss occurs due to the restriction created by the orifices in the plate, which leads to energy dissipation.

Parameter | Standard units | Description |
---|---|---|

Flow | m³/s | Volumetric flow rate through the pipe |

Diameter | mm | Pipe diameter |

Number of orifices | - | Number of orifices on the plate |

Orifice diameter | mm | Diameter of each orifice |

Parameter | Standard units | Description |
---|---|---|

Head loss | m | Amount of energy dissipated in the system due to flow restriction |

Flow | l/s | Final volumetric flow rate after calculating head loss |

This method determines the orifice diameter based on the desired flow rate, pipe diameter, and head loss. It is useful for designing custom orifice plates to meet specific system requirements.
