流量孔英文术语

1. What is the definition of a flow orifice?

A flow orifice is a device used to measure fluid flow by

creating a restriction in the flow path. This restriction

causes a pressure drop across the orifice, which can be

measured to determine the flow rate.

流量孔是一种用于测量流体流量的设备，通过在流动路径中创建

限制来实现。这种限制造成了一个压降，可以测量以确定流量。

2. What are the different types of flow orifices?

There are several types of flow orifices, including

concentric, eccentric, segmental, and quadrant edge. Each

type has its own unique design and application.

有几种类型的流量孔，包括同心、偏心、段状和象限边缘。每种

类型都有其独特的设计和应用。

3. What is the purpose of a flow orifice plate?

A flow orifice plate is used to create a restriction in

the flow path, which causes a pressure drop across the

plate. This pressure drop can be measured to determine the

flow rate of the fluid.

流量孔板用于在流动路径中创建限制，这会导致板上的压降。可

以测量这个压降来确定流体的流量。

4. What is the difference between a flow orifice plate

and a flow nozzle?

A flow orifice plate creates a restriction in the flow

path by using a circular orifice, while a flow nozzle uses

a converging section followed by a diverging section to

create a pressure drop. Flow nozzles are typically used for

high flow rates, while flow orifice plates are used for

lower flow rates.

流量孔板通过使用圆形流量孔在流动路径中创建限制，而流量喷

嘴则使用收敛段后的扩散段来创建压降。流量喷嘴通常用于高流量，

而流量孔板用于较低的流量。

5. What is the Reynolds number?

The Reynolds number is a dimensionless quantity used in

fluid mechanics to predict the flow regime of a fluid. It

is calculated based on the fluid velocity, density,

viscosity, and characteristic length of the flow path.

雷诺数是流体力学中用于预测流体流动状态的无量纲量。它是根

据流体速度、密度、粘度和流动路径的特征长度计算的。
