The present invention is a method for determining at least the flow velocity or fluid volume flow rate (5) of a fluid flowing through an implanted vascular assist system (1), the ultrasonic sensor (2) of the vascular assist system (1). Step a) to perform pulse Doppler measurement using)...
Physicists and engineers use Poiseuille's law to predict the velocity of water through a pipe. This relationship is based on the assumption that the flow is laminar, which is an idealization that's more applicable to small capillaries than to water pipes. Turbulence is almost always a factor ...
I have a long vertical pipe in which the flow is almost straight and vertical. Now I want to find out the angle of flow with respect to the Y-axis (just to make sure that the angle wrt Y-axis is less than 15 deg). How can I do that, generally? I had the problem solved in ...
In some cases, where system components are subject to drift, or where extreme accuracy is required, a calibration procedure may be used many times a day. In other cases, where long-term stability of components is good, calibration may only occur once a week or once a month. Without such ...
pV flow is a measure of the mass flow of the gas; the temperature to be indicated here. Pump throughput qpV The pumping capacity (throughput) for a pump is equal either to the mass flow through the pump intake port: (1.9) or to the pV flow through the pump’s intake port...
It's flow rate, as we'll see below. The velocity (or superficial velocity) of a fluid is a measure of the average speed and direction the particles of the fluid are moving. It answers the question "how fast?" It's an important parameter when a fluid is being ...
Volumetric flowmeters directly measure the volume of fluid (Q) passing through the flowmeter. The only flowmeter technology that measures volume directly is the positive displacement flowmeter. Velocity flowmeters utilize techniques that measure the velocity (v) of the flowing stream to determine the ...
Dear all, I would like to ask how can I find the flow velocity of a specific point (x=105, y=2.5) in my channel (it is shown in the picture). In the graph, if I click at any random point I got 3 values: on the x axis I got the channel's length, on the y axis t...
Pitot tubes are used to measure airflow velocity, but advanced tunnels deploy laser anemometers that detect wind speed by "seeing" airborne particles in the airstream. Pressure probes monitor air pressure and water vapor pressure sensors track humidity. In addition to sensors, visual observations ...
An Orifice Meter is used to measure the rate of flow of Liquid, Gas, or steam using the differential pressure measurement principle.
