Flow Rate Equation:
From: | To: |
The hose flow rate equation calculates the volumetric flow rate of a fluid through a hose or pipe based on pressure difference and fluid properties. It's derived from Bernoulli's principle and is commonly used in fluid dynamics and engineering applications.
The calculator uses the flow rate equation:
Where:
Explanation: The equation calculates how much fluid volume passes through a cross-section per unit time based on the pressure driving force and fluid properties.
Details: Accurate flow rate calculation is essential for designing fluid systems, determining pump requirements, optimizing pipe sizes, and ensuring efficient operation in various industrial and engineering applications.
Tips: Enter cross-sectional area in m², pressure difference in Pa, and fluid density in kg/m³. All values must be positive numbers greater than zero.
Q1: What units should I use for this calculation?
A: The calculator uses SI units: m² for area, Pa for pressure, and kg/m³ for density. Convert your measurements to these units before calculation.
Q2: Does this equation work for all fluids?
A: This equation works best for incompressible fluids with relatively low viscosity. For highly viscous fluids or compressible gases, more complex equations may be needed.
Q3: What factors affect flow rate accuracy?
A: Factors include pipe roughness, fluid viscosity, temperature effects on density, and the presence of fittings or bends in the system.
Q4: How does pipe diameter affect flow rate?
A: Flow rate is proportional to the cross-sectional area, which increases with the square of the diameter. Doubling the diameter quadruples the flow rate for the same pressure difference.
Q5: When is this equation not appropriate?
A: This simplified equation may not be accurate for very long pipes, turbulent flow, or systems with significant friction losses that aren't accounted for in the basic formula.
