Instrument for measuring air velocityFALES ELISHA N.US1517350 * Dec 15, 1921 Dec 2, 1924 Fales Elisha N Instrument for measuring air velocity
Air velocity (miles per hour) 0.5~44.7 mile/h Air velocity (nautical miles per hour) 1.0~31.1 knots Air velocity (feet/per minute) 40~3940 ft/min Air velocity Accuracy ±(5%+1d) value or Full scale ±(1%+1d) [Take which is the largest] Air Temperature Measuring Range 0~50°C (32...
The testo 400 Universal measuring tool is used to determine reliable results of the indoor climate. Here the measuring programs for PMV/PPD and draught rate are already stored in the instrument. The flexible attachment of various probes is another plus point of the testo 400 for me. If my ap...
the speed or length of conveyor belts and goods sold by the metre can also be measured using contact measurement via a measuring wheel. There is also the possibility of determining the rpm of rotating objects without contact using a reflection mark and a light beam emitted by the instrument. ...
This instrument has a bulb Suggestions recently have been put forward for the which is warmed to just above the average temperature heating of trams, and the roofing over of the outside of the human skin, and its rate of cooling is measured seats of buses has been discussed. There have ...
Parallel to the sampling probe, a type S pitot tube measured the pressure difference (ΔP) between the two openings, from which the stack flow velocity and flow rate were calculated (U.S. EPA, 1991). Flow velocities measured by this method across the stack diameter demonstrated < 3% variati...
Their maximum air velocity was 0.6ms−1. Mills and Lyn (2002) measured the air-flow resistance of rebonded PU foam, and fitted Δp vs. V data (Fig. 8.3) with equation (8.2). The B and K values (Table 8.1) decreased linearly with increasing compressive strain. However it was not...
(CO, ± 1 ppm), nitrogen oxides (NOx, ± 0.1 ppm), and sulfur dioxide (SO2, ± 1 ppm) were measured by electrochemical sensors. Measurements were conducted once per second. PM2.5was investigated by laser particulate matter analysis instrument (LC-5C, ± 0.001mg/m3), ...
(round) jets can be referred to. The principle is to generate such high air velocity that a shield against pressure difference, temperature difference, andwind velocityis sustained. However, it is not possible to have complete separation by an air curtain. The main reason is that the jet en...
The ratio of the actual amount of water vapor present in the air at a given temperature to the maximum amount that the air could hold at that temperature. Relative humidity is expressed as a percentage. Compareabsolute humidity. The American Heritage® Student Science Dictionary, Second Edition...
