The pressure difference across the horizontal opening was changed by controlling the air supply to and exhaust from the space above the opening. Smoke and air flow patterns were either downward uni-directional flow of air, bi-directional flow of air and smoke or uni-directional flow of smoke ...
The measurement of the flow of gases or liquids can be performed using a restriction which causes a pressure drop. The volume flow rate is usually proportional to the square root of the pressure difference. These types of transducers are called differential pressure or dp flowmeters. They may ...
Measurement of the oil-water flow is of great importance in the industrial process. In the paper, a soft-measurement method for oil-water mass flow-rate was brought forward, in which the V-cone differential pressure meter was used and the adaptive wavelet network was developed to achieve the...
The pressure difference between the inlet and the outlet of the structure is monitored as a function of time. Thus the gas- transfer-rate is evaluated and compared with experimental data, in order to verify the departure from the standard Navier-Stokes equations with the no-slip boundary ...
According to the customer's specific requirements, the flow meter of the corresponding gas type and range can be selected. B channel: 0~300SCCM N2 gas C channel: 0~500SCCM Ar gas measurement accuracy ±1.0%F.S Pipe pressure resistance 3MPa Working pressure differ...
质量流量入口设定的静压值(Supersonic/Initial Gauge Pressure)主要用于超声速流动或想要将该边界用于初始化时。 当流动为亚音速时,对话框中设定的静压值被忽略。 指定入口静压 3 质量流量入口边界计算 当采用质量流边界入口条件时,软件会计算该边界上每个网格面的速度,并利用该速度计算其他所有与之相关求解变量进入计算...
I am measuring the mass flow at the outlet and as the runners are different in shape and length, mass flow are is different. What is the best way to describe the difference. Does it depend on length only or length, shape or what other factors can cause the change in mass flow rate....

Volumetric flow rate is the volume of fluid that passes per unit of time. Flow meter technologies such asdifferential pressure, magnetic, thermal, turbine, ultrasonic, and vortex all measure flow rate as a function of fluid velocity. Please refer to the respective flow meter datasheet for detail...
where A is the water permeability (m/s Pa) and ΔP is the hydraulic pressure difference (Pa). 17.2.3 Some Results on This Process According to the developed expressions, defining the interface concentrations, the solute transfer rates, and the water flux, a few typical figures will be shown...
