Flow Rate Equation:
| From: | To: |
The flow rate equation (Q = A × v) calculates the volumetric flow rate of a fluid through a cross-sectional area. It's a fundamental equation in fluid dynamics used to determine how much fluid passes through a given point per unit time.
The calculator uses the flow rate equation:
Where:
Explanation: The equation multiplies the cross-sectional area through which the fluid flows by the average velocity of the fluid to determine the volumetric flow rate.
Details: Flow rate calculation is essential in various engineering applications, including pipe sizing, pump selection, irrigation systems, and hydraulic analysis. It helps ensure proper fluid transport and system efficiency.
Tips: Enter cross-sectional area in square meters (m²) and velocity in meters per second (m/s). Both values must be positive numbers greater than zero.
Q1: What units should I use for the inputs?
A: The calculator uses SI units: square meters (m²) for area and meters per second (m/s) for velocity. Make sure to convert your measurements to these units before calculation.
Q2: Can this calculator be used for any fluid?
A: Yes, the equation Q = A × v applies to all Newtonian fluids flowing through a defined cross-section, regardless of the fluid type (water, oil, air, etc.).
Q3: What if the cross-section is not uniform?
A: For non-uniform cross-sections, you may need to calculate the average area or use integration methods for more precise results.
Q4: Does this account for fluid viscosity?
A: The basic equation Q = A × v does not directly account for viscosity. For more complex fluid dynamics involving viscosity, additional equations may be needed.
Q5: How accurate is this calculation?
A: The calculation provides a theoretical flow rate based on the inputs. Actual flow rates may vary due to factors like friction, turbulence, and fluid properties.
