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...
I set the massflow rate for the straight pipe, and obtain a pressure drop from the boundary monitoring information in the .erd file. I then input this pressure drop back into the straight pipe, but obtain a massflow rate out that is an order of magnitude higher than the original, despite...
This issue also persists when pulling in the pressure outlet mass flow report into a user code with the mass flow inlet having a difference in flow rate still. I'm hoping to have this work for multiple angles of attack since the ratio between the outlet and inlet mass ...
Roughness elements on natural surfaces exert a drag on the flow due to the difference in pressure between the windward and the leeward sides of the element. Consequently, the transfer of momentum from the flow to the surface involves a complex process depending on the viscous and pressure forces...
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....
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 diff...
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...
With the increase in the flow ratio, the pressure ratio (difference between inlet pressure and suction pressure divided by the difference between exit pressure and suction pressure) falls off while the efficiency presents a parabolic distribution. The pressure ratio can be promoted by properly ...
