1. What is a Restriction Orifice Plate Size Calculator?

Definition: This calculator determines the required diameter of a restriction orifice plate based on flow rate and desired flow velocity.

Purpose: It helps engineers and technicians design restriction orifice plates for fluid control systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( d \) — Orifice diameter (meters)
• \( Q \) — Flow rate (cubic meters per second)
• \( v \) — Flow velocity (meters per second)
• \( \pi \) — Mathematical constant Pi (~3.1416)

Explanation: The formula calculates the diameter needed to achieve a specific flow velocity for a given volumetric flow rate.

3. Importance of Orifice Plate Sizing

Details: Proper orifice sizing ensures accurate flow control, prevents excessive pressure drops, and maintains system efficiency.

4. Using the Calculator

Tips: Enter the flow rate in m³/s and desired flow velocity in m/s. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a restriction orifice plate?
A: It's a device used to restrict flow and reduce pressure in piping systems by creating a controlled pressure drop.

Q2: What are typical flow velocities used?
A: Common velocities range from 0.5-10 m/s depending on application, with 1-3 m/s being typical for many liquids.

Q3: Does this account for fluid properties?
A: This basic calculation assumes ideal conditions. For precise work, consider fluid density, viscosity, and discharge coefficients.

Q4: How do I convert other flow units to m³/s?
A: 1 m³/s = 1000 L/s = 60,000 L/min = 35.315 ft³/s = 15850.3 gallons/min (US)

Q5: What about pressure drop calculations?
A: Pressure drop depends on additional factors like fluid properties and orifice geometry not included in this basic calculator.
