Flow Equation:
| From: | To: |
The differential pressure to flow equation describes the relationship between flow rate and pressure difference in fluid systems. It's commonly used in various engineering applications where flow measurement is based on pressure differentials.
The calculator uses the flow equation:
Where:
Explanation: The equation shows that flow is proportional to the square root of the pressure difference, with the constant k representing system-specific characteristics.
Details: Accurate flow calculation is essential for system design, performance monitoring, and efficiency optimization in various fluid systems including pipelines, HVAC systems, and industrial processes.
Tips: Enter the system constant k and the pressure difference in psi. Both values must be valid (k > 0, ΔP ≥ 0).
Q1: How is the constant k determined?
A: The constant k is specific to each system and is typically determined through calibration or provided by equipment manufacturers based on system characteristics.
Q2: What are typical units for flow measurement?
A: Flow can be measured in various units including GPM (gallons per minute), L/min (liters per minute), or CFM (cubic feet per minute), depending on the application.
Q3: When is this equation applicable?
A: This equation is commonly used for incompressible fluids and in systems where flow is measured using differential pressure devices like orifice plates or venturi meters.
Q4: Are there limitations to this equation?
A: Yes, this simplified equation assumes ideal conditions and may need adjustments for viscosity, temperature, and specific system configurations.
Q5: Can this be used for gas flow calculations?
A: For gases, additional factors like compressibility and temperature often need to be considered, requiring more complex equations.
