Flow Rate Formula:
Definition: This calculator determines the volumetric flow rate through a pipe based on its cross-sectional area and the fluid velocity.
Purpose: It helps engineers, plumbers, and fluid system designers understand pipe capacity for proper system design and analysis.
The calculator uses the formula:
Where:
Explanation: The flow rate is simply the product of the pipe's internal area and the average velocity of the fluid.
Details: Accurate flow rate calculations ensure proper pipe sizing, prevent overpressure situations, and maintain efficient system operation.
Tips: Enter the pipe's cross-sectional area in m² and the fluid velocity in m/s. For circular pipes, area = π × (diameter/2)².
Q1: How do I calculate area for a circular pipe?
A: Use the formula A = π × r² where r is the pipe's internal radius in meters.
Q2: What's a typical water velocity in pipes?
A: Domestic water systems typically use 0.5-2.5 m/s, while industrial systems may go higher.
Q3: Does this work for any fluid?
A: Yes, as long as you know the velocity. Note that velocity depends on fluid properties and pressure.
Q4: How does pipe material affect capacity?
A: Material affects friction losses which may reduce velocity, but the basic capacity calculation remains the same.
Q5: Can I use this for partially full pipes?
A: No, this assumes full pipe flow. For partially full pipes, more complex calculations are needed.
