Flow Rate Equation:
| From: | To: |
Flow rate (Q) is the volume of fluid that passes through a given cross-sectional area per unit time. It is a fundamental concept in fluid dynamics and is measured in cubic meters per second (m³/s) in the SI system.
The calculator uses the flow rate equation:
Where:
Explanation: The equation calculates the volumetric flow rate by multiplying the cross-sectional area through which the fluid flows by the average velocity of the fluid.
Details: Flow rate calculation is essential in various engineering applications, including pipe sizing, pump selection, irrigation systems, and hydraulic analysis. It helps in designing efficient fluid transport systems and ensuring proper fluid dynamics in various processes.
Tips: Enter the cross-sectional area in square meters (m²) and the velocity in meters per second (m/s). Both values must be positive numbers. The calculator will compute the flow rate in cubic meters per second (m³/s).
Q1: What units should I use for the inputs?
A: The calculator expects cross-sectional area in square meters (m²) and velocity in meters per second (m/s). If you have measurements in other units, convert them first.
Q2: Can this calculator be used for any fluid?
A: Yes, the equation Q = A × v applies to all Newtonian fluids, provided the flow is steady and the velocity profile is uniform across the cross-section.
Q3: What if the cross-section is not circular?
A: The equation works for any cross-sectional shape. Simply calculate the area appropriately for the shape (e.g., rectangle, ellipse, etc.).
Q4: How accurate is this calculation?
A: The calculation assumes uniform velocity distribution. In real applications, velocity profiles may vary, so this gives an idealized result.
Q5: What are typical flow rate values in engineering applications?
A: Flow rates vary widely depending on the application. Domestic water systems might have flow rates of 0.0001-0.01 m³/s, while large pipelines can handle 10+ m³/s.
