1, flow (instantaneous flow) = pipeline cross-sectional area x flow.

2. Flow (hourly flow) =3600 x pipeline cross-sectional area x flow?

Where: pipeline cross-sectional area =πxRxR

In which: flow unit: cubic meter/hour; Flow unit: m/s; Radius unit: meter; 3600 is the number of seconds converted from 1 hour.

Extended data:

The measurement of fluid flow in a certain channel is collectively called flow metering.

There are various fluids used for flow measurement, such as gas, liquid and mixed fluid. The temperature, pressure and flow rate of fluid are very different, and the required measurement accuracy is also different. Therefore, the task of flow measurement is to study various corresponding measurement methods according to the measurement purpose, the type of measured fluid, the flow state, the measurement location and other measurement conditions to ensure the correct transmission of flow values.
