1.1 When to Use Each Formula 2. Calculating Flow Rate of Ideal Fluid 3. Calculating Flow Rate with Pressure What is Flow Rate Flow rate, often denoted as 'Q', is an essential metric in numerous engineering fields. It helps to quantify the volume of fluid passing per unit of time un...
The flow rate formula shows that the volume of fluid flowing in a specific time period is equal to the velocity at which the fluid is travelling multiplied by the cross-sectional area it is travelling through. {eq}Q = v \times A {/eq} Where: Q is volumetric flow rate symbol. The flo...
Pump Flow Rate Formula The pump flow rate formula is an essential aspect of many engineering projects. Accurate calculations ensure the efficiency, reliability, and effectiveness of your systems — from simple water pumps to complex industrial processes. The basic formula to calculate the pump flow r...
The flow rate of a fluid can be calculated using the volumetric flow rate equation: Q = A × v Thus, the volume flow rate Q is equal to the cross-sectional area of the pipe A times the velocity of the fluid v.[2] To use the flow rate formula, substitute the cross-sectional area...

The volumetric flow rate formula may be written in the alternative (read: way more useful) form. You can first calculate the volume of a portion of the fluid in a channel as: V=A⋅lV = A\cdot lV=A⋅l whereAis a cross-sectional area of the fluid, andlllis the width of a give...
Example 1:A round pipe has a diameter of 25 mm and water is running through it with a velocity of 10 m/s. What is the flow rate of the water? First, we calculate the cross-section area to be (25/2)^2 · 3.1416 ~= 490.875 mm2via thearea of a circle formula. We can convert ...
Flow velocityfor a given flow rate and internal pipe diameter. Mass or volume flow rate conversions, using fluid density. If working with perfect gases, you can convertvolume flow ratebased on pressure and temperature changes. This is useful for pipelines withpressure-reducing valvesor varying cond...
If required, it is advisable to select a valve with a Cv value higher than the calculated one. This provides you with a greater flow rate and it safeguards against potential changes in pressure or flow rate. 如果需要,建议选择Cv值高于计算值的阀门。这为您提供了更大的流量,并防止压力或流量的...
