The so-called flow rate refers to the amount of fluid flowing through the effective cross section of closed pipeline or open channel in unit time, also known as instantaneous flow rate. When the amount of fluid is expressed by volume, it is called volume flow; When the amount of fluid is expressed by mass, it is called mass flow. The volume of fluid flowing through a section of pipeline in unit time is called the volume flow of the section. Referred to as flow, expressed by Q.

Chinese name: transportation

Type: physical nouns

Unit: cubic meters per second

Abbreviation: q

basic concept

The unit is cubic meters per second, so the equation of flow is:

Q=Sv= constant.

(s is the cross-sectional area and v is the water flow velocity)

When the incompressible fluid flows stably, the flow through each section of the same flow tube is constant.

Measuring the flow of fluid flowing 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.

Generally speaking, website traffic refers to the number of visits to a website, which is used to describe the number of users visiting a website and the number of pages visited by users. Commonly used statistical indicators include the number of independent users of the website, the total number of users (including repeat customers), the number of pages visited, the number of pages visited by each user, and the average stay time of users on the website.
