4) volume type air flow 体积空气流量 例句>> 5) volume flux 体积流量 1. This spread is proved clearly to be equivalent by comparing volume flux of incompressible fluid calculated in Cartesian coordinate and column coordinate with proper approximation. 详细推导出在合理近似的条件下,展开前后不同...
The invention relates to a device for measuring the volumetric flow of air, comprising two temperature-dependent resistances which are fed by power sources and whose resistance values are used to measure mass and temperature. A read-out signal proportional to the volume of air is created by ...
The volumetric flow rate to be specified is V˙3. This is the actual volumetric flow rate of air that will be drawn into the exhauster. The critical design parameter for a pneumatic conveying system is the conveying line air velocity, C1, at the material feed point into the pipeline. This...
The room pressure only remains constant where the quantity of intake and outlet air is equal. This can be achieved with a constant volume flow system through fine tuning of the air control system. Through tolerances in the intake and outlet air quantities, with a variable volumetric flow system...
Wonderingwhat is mass flowandwhat is volumetric flow? Let’s see it this way: Assume you have a 1.0 litre cylinder with a movable piston of negligible weight that closes it. Secondly, assume that this cylinder holds 1.0 litre of air at ambient pressure (1 atm) and 0oC temperature. This...

The invention relates to a volume flow regulator for air-conditioning and ventilation systems with a flap (3) which is pivotable in a flow duct and the pivot shaft (2) of which has a lever arm (11), on which a spring (5) engages in an articulated manner. In order to indicate a me...
rate of flow,flow cardiac output- the amount of blood pumped out by the ventricles in a given period of time; "a resting adult has a cardiac output of about three quarts a minute" rate- a magnitude or frequency relative to a time unit; "they traveled at a rate of 55 miles per hour...
The application of the volumetric flowmeter to measure large flow gas is probed. Combining th... XH Nie,YF Zhang,MY Cao - 《Gas & Heat》 被引量: 11发表: 2000年 Simultaneous Measuring Method for Both Volumetric Flow Rates of Air-Water Mixture Using a Turbine Flowmeter A turbine flowmeter ...
A Flow Bench is a basic system to measure and display volumetric air flow. It is used as a tool for measuring and quantifying modifications and improvements made to items such as automotive cylinder heads and carburettors by measuring the volume of air that they can flow within a set time pe...
