  • How do you calculate volumetric flow rate from flow velocity?

  • The volumetric flow rate can be calculated as the product of the cross sectional area (A) for flow and the average flow velocity (v). If area is measured in square feet and velocity in feet per second, Equation 3-1 results in volumetric flow rate measured in cubic feet per second.

  • What is volume flow rate of fluid?

  • The volume flow rate of a fluid is defined to be the volume of fluid that is passing through a given cross sectional area per unit time. The term cross sectional area is just a fancy term often used to describe the area through which something is flowing, e.g., the circular area inside the dashed line in the diagram below.

  • What is the symbol for volume flow rate?

  • The symbol Q is often used to represent volumetric flow rate (in calculus terms, V虈 is sometimes used to represent the rate of change of volume velocity or volumetric flow). The SI unit is cubic metres per second ( m3/s ).

  • What units are used to measure volumetric flow?

  • If area is measured in square feet and velocity in feet per second, Equation 3-1 results in volumetric flow rate measured in cubic feet per second. Other common units for volumetric flow rate include gallons per minute, cubic centimeters per second, liters per minute, and gallons per hour.
