### Flow Rate Calculator - Finding Volumetric and Mass Flow Rate

Volumetric and mass flow rate. When we talk about flow rate, you most likely picture the concept of volumetric flow rate (also known as rate of liquid flow, volume flow rate or volume velocity). The volumetric flow rate can be defined as the volume of a given fluid that passes through a given cross-sectional area per unit of time If the volume flow rate of the fluid is known, it needs to be converted into a mass flow rate, which can be done with the formula: qm=qv×ρ. Density, Mass Flow, and Volumetric Flow. A description on the relationship between density, mass flow rate and volumetric flow rate. The following video provides a good explanation

those variables are related by a relation from the definition of density. which is $\rho = mass / volume.$ by multiplying equation above by $1/s / 1/s$ , we can change both mass and volume by their rate. so that, [math]\rho =.. Standard volumetric flow rates of a fluid are the equivalent of actual volumetric flow rates in the sense that they have an equal mass flow rate. This identity makes standard volumetric flow appropriate providing a common baseline for comparison of volumetric gas flow rate measurements at different conditions. This article outlines how to convert between standard and actual volumetric flow rates When a volume flow rate is calculated a chart will be generated showing related conversion values for mass versus volume flow for the specified substance density. Formula. The formula used by this calculator to calculate the volume flow is: Q = ṁ / ρ. Symbols. Q = Volumetric flow rate; ṁ = Mass flow rate; ρ = Density; Mass Flow Rate.

Easily calculate the volumetric flow rate of a pipe (a.k.a. discharge rate) given its diameter (for a round pipe, height & width for a rectangular one) and the velocity of the liquid or gas flowing through it. The flow rate calculator can also calculate the mass flow rate of liquids given the liquid density is known. Input and output support metric and imperial. Mass flow rate can also be calculated by: ˙ = ⋅ ˙ = ⋅ ⋅ = ⋅ where: ˙ or Q = Volume flow rate, ρ = mass density of the fluid,; v = Flow velocity of the mass elements,; A = cross-sectional vector area/surface,; j m = mass flux.; The above equation is only true for a flat, plane area. In general, including cases where the area is curved, the equation becomes a surface integral The volumetric flow rate in a heating system can be expressed as. q = h / (c p ρ dt) (1). where. q = volumetric flow rate (m 3 /s). h = heat flow rate (kJ/s, kW). c p = specific heat (kJ/kg o C). ρ = density (kg/m 3). dt = temperature difference (o C). This generic equation can be modified for the actual units - SI or imperial - and the liquids in use Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate

Dividing the volumetric flow by the time, in hours, gives the volumetric flow rate in cubic feet per hour. Be consistent with your use of measurement units in flow calculations. If you use a mass expressed in pounds, a density expressed in pounds per cubic foot and a time expressed in hours to calculate a volumetric flow rate, for example, then the result must be expressed as cubic feet per hour

Volume flow rate is a term in physics that describes how much matter - in terms of physical dimensions, not mass - moves through space per unit time. For example, when you run a kitchen faucet, a given amount of water (which you might measure in fluid ounces, liters or something else) passes out of the opening of the faucet in a given amount of time (usually seconds or minutes) Volumetric flow rate is a measure of the 3-dimensional space that the gas occupies as it flows through the instrument under the measured pressure and temperature conditions. Volumetric flow rate can also be called actual flow rate. Mass flow rate is a measure of the number o
