Although a pitot tube interferes with the near-probe flow field, its construction, setup and utilization are easy, and consequently it is widely used in performance tests of turbomachines to extract velocity, flow rate and pressure components. Hot-wire and hot-film anemometers work on the basis...
In this regard, an experiment to investigate the effect of DTR and labor intensity on human bodies was conducted in a climate chamber, and three radiation intensities (0.0 kW/m2, 1.0 kW/m2, 2.0 kW/m2) and two labor intensities (4.5 km/h, 6.0 km/h) were selected as experimental ...
and 36% of global greenhouse gas (GHG) emissions are due to operational energy demands of buildings in industrialised countries. This impact is even larger if the embodied energy associated with the building materials is included [11]. Embodied energy is the primary energy that is used in the ...
interspersed with all kinds of things that could be “houses” for other things: teapots/houses for tea; hangars/houses for airplanes; pea pods/ houses for peas; shoes/ houses for feet; on and on and on until it concludes that the earth is a house for us/it All!We were ready to ta...
It is a simple science fair project to demonstrate how lemons react when they come into contact with different types of acids, such as vinegar and baking soda. The results are interesting to observe and can be used as an experiment for younger students who are just beginning their study of ...
they have a grid of weather stations and anemometers which provide wind speed data for wind power prediction up to 12 hours ahead. This grid is linked and computerised for constant real time prediction. Predictions are made for future times at short intervals up to 12 hours ahead....
NOAA’s Pacific Marine Environmental Lab (PMEL) has been an active partner with Saildrone and is leading this year’s hurricane-PMEL experiment with five of the hurricane Saildrones in the Atlantic. A really good national investment. The hope is that a network of Saildrones will lay...
Time-height plots of data from vertical arrays of anemometers were the first to show unequivocally that the transfer events were coherent through the roughness sublayer and that the sweep events corresponded to displacement of canopy air by the coherent airmass of a canopy scale eddy. Fig. 2.5...
With a three-wire sensor, all three velocity components can be determined. As well as wire-type sensors, there are hot-film sensors, which are more robust but, due to a larger thermal inertia, are not as fast-responding as wires. Modern hot-wire anemometers are normally used in the CT...
Heatflow measurementcan be performed atsteady stategrowth conditions (in that case the heat flow signal does not vary with time and is not affected by thedynamicsof the measurements) or under dynamic growth conditions, for example after apulseof substrate or during a batch experiment. Under dynam...
