Gas Flow Equation:
| From: | To: |
The gas flow equation calculates the volumetric flow rate of a gas through a given cross-sectional area. It's a fundamental equation in fluid dynamics used to determine how much gas passes through a specific point per unit time.
The calculator uses the gas flow equation:
Where:
Explanation: The equation multiplies the cross-sectional area through which the gas flows by the velocity of the gas to determine the volumetric flow rate.
Details: Accurate gas flow calculation is crucial for designing ventilation systems, calculating fuel consumption, monitoring industrial processes, and ensuring proper functioning of various mechanical systems that involve gas movement.
Tips: Enter the cross-sectional area in square meters and the gas velocity in meters per second. All values must be valid positive numbers.
Q1: What units should I use for the inputs?
A: The calculator expects area in square meters (m²) and velocity in meters per second (m/s) for consistent results in m³/s.
Q2: Can this calculator be used for liquids as well?
A: Yes, the same equation applies to incompressible fluids, though for compressible gases under varying pressure, additional factors may need consideration.
Q3: What is a typical gas flow rate in ventilation systems?
A: Typical values range from 0.5 to 5 m³/s for residential systems, while industrial systems can handle much higher flow rates.
Q4: How does temperature affect gas flow calculations?
A: Temperature affects gas density and viscosity, which can influence velocity measurements. For precise calculations, temperature compensation may be necessary.
Q5: What if the cross-section isn't circular?
A: The equation works for any cross-sectional shape as long as you use the correct area measurement for that shape.
