The Daniel Orifice Flow Calculator is a vital instrument used to determine the flow rate of fluids through an orifice, such as a small hole or opening. It does this by applying a specific formula that takes into account various parameters, including the discharge coefficient (Cd), orifice area (A), pressure drop (ΔP), and fluid density (ρ). This tool is invaluable in a wide range of industries, including oil and gas, chemical processing, and fluid transport.
Formula of Daniel Orifice Flow Calculator
The heart of the Daniel Orifice Flow Calculator lies in its formula, which is expressed as follows:
Q = Cd * A * √((2 * ΔP) / ρ)
Where:
- Q represents the flow rate and can be measured in cubic meters per second or any other appropriate units.
- Cd is the discharge coefficient, a dimensionless constant that depends on the shape and size of the orifice plate. For standard orifice plates, Cd typically falls within the range of 0.6 to 0.8.
- A denotes the area of the orifice, measured in square meters.
- ΔP represents the pressure drop across the orifice, measured in Pascals.
- ρ stands for the density of the fluid, measured in kilograms per cubic meter.
This formula allows engineers and technicians to accurately calculate the flow rate of various fluids, making it an indispensable tool for a variety of applications.

Example of Daniel Orifice Flow Calculator
Let’s illustrate the application of the Daniel Orifice Flow Calculator with an example. Suppose we have an orifice with an area of 0.02 square meters, a discharge coefficient of 0.7, a pressure drop of 5000 Pascals, and a fluid density of 1.2 kg/m³. Using the formula, we can calculate the flow rate as follows:
Q = 0.7 * 0.02 * √((2 * 5000) / 1.2)
Q ≈ 0.409 m³/s
This result provides us with the flow rate through the given orifice.
