There are actually quite a fewcreatures that could survive an apocalypse, but none are quite so hardy as the tardigrade. First discovered in 1773 by German pastor J.A.E. Goeze, these miniscule animals measure less than 1 mm in length, have eight legs with four to six claws on each, and...
Often in a CFD model I want to know about the fluid flow rate passing through a heat sink and not just the solid temperature. After all, there’s a lot to consider inheat sink designandoptimisation. In Simcenter Flotherm XT although you can’t extract fluid data directly from the...
After obtaining the Flow Velocity from the previous procedure, that figure is nowmultiplied by the Duct Cross Sectional Areato determine the Air Flow in CFM. How do I calculate CFM for a room? How to Calculate the CFM of a Room Measure the room's width and length. ... ...
There are many other ways of approximating the lift curve coefficient. Because the lift coefficient needs to comprise many different factors affecting aircraft flight, you can also use it to measure the angle a plane might take with respect to ground. This angle is known as angle of attack (A...
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 ...
instruments used to measure air velocity, air flow rates and temperature. TSI-Alnor aircones are accessories for our vane anemometers, used to quickly and easily measure air flows in applications in which traditional capture hoods are too large to use or the air flow is too...
The frequency of the resulting pulse train is a measure of flow rate, while the total number of pulses gives the size of the batch. While PD meters are operated by the kinetic energy of the flowing fluid, metering pumps determine the flow rate while also adding kinetic energy to the fluid...

In essence, ultrasonic measurement of wind speed and direction leverages the influence of wind speed on the velocity of sound. This method of measurement provides insight into the quantification of numerous physical variables. It is my hope that understanding how ultrasonics measure wind speed will ...
If you want to calculate the flow rate of water or air in cubic feet per second, you need to measure the cross-sectional area of the pipe or duct in feet and measure the velocity of the water or air in feet per second, then use Q = A×v. For pressurized
