Volume Flow Converter

Volume flow concept is mainly seen in the engineering and physics, the concept of volumetric flow rate indicate the volume flow with respect to time. Now order to understand this we can consider a situation you want to water your garden and you have fixed pipe on the tap as soon as the tap is opened the water will flow out from the pipe, now the amount of water released from the pipe in a particular interval of time can be considered as the volume flow of that pipe. Here one thing to consider is that we should not be confused with volumetric flux. mainly the idea is to measure the rate of flow of fluid with respect to time.

We need to use limits in order to define the volumetric flow rate. here we have Q= dV/dt, this shows the rate of change of volume with respect to time is considered as the volume flow, here in addition to this one thing that we have to consider is that it is just a time derivative and hence this is a scalar quantity, after some certain boundary is crossed when we consider the change in volume flow.

Calculation and formula

Q= v.A, this formula is used to define volume flow, here in this formula, v is the velocity with which a particular fluid is flowing and A is the area of cross-section, here in order to use this equation we have to consider only plane cross-section, now if we consider the curved surface then we have to use integration were we integrate he v with respect to A as,

Q= ʃʃ v.dA this is the equation which governs the area which is required to calculate the volumetric flow rate, with this equation you can calculate the flaw rate on any type of surface, here one thing to consider that the vector area is a combination of magnitude of the area form the volume of the fluid will pass.

We have seen that the volume flow is actually the dot. The product of two other vector quantity and this is because the only volume flowing through the main cross-section is the amount normal area and this should be parallel with the unit area, we have an equation to understand this as

Q= vAcosC, where, Q is the volume flow and v is the amount of fluid flowing and A is the area of the cross-section while c is the angle between both of them. Here one thing is very interesting the amount of fluid passing through the area of cross section depends on the factor cos C and with an increase in the angle the amount of fluid flowing also increases.


The unit of this physical quantity is meter cube per second. that is m*m*m per second and in addition to this, there is one more unit which is widely used is sccm which means standard cubic centimeter per minute.
