Volume flow rate is to be determined from measurements of volume and time period.
Volume flow rate is used to describe the flow of fluids (gases and liquids) in pipes, ducts, and vessels. It’s essential in designing and optimizing systems, such as:
- Water supply networks
- HVAC systems
- Chemical processing plants
- Oil and gas pipeline
The volume flow rate formula is:
Q = ΔV / Δt
where:
- Q is the volume flow rate (m³/s)
ΔV
is the volume of the fluid that is varying (gal)Δt
 is the variation of time (s)
