The resistance, R, to air flow passing through a tube is determined by the radius, r, and the length, l, of the tube, as well as by the physical properties of the gas breathed (μ), according to the following formula: R = 8μlr4 This points out the critical importance of the radi...
Airflow Velocity Measurement Techniques. Accurately mmeasure airflow in mines with rotating vane anemometer, velometer, pitot tube, and ultrasonic flowmeters.
In this regard, the reverse conversion 105 for compensating the response is performed, according to the formula, using the time constant τ, the period T for A/D conversion, the first time A/D converted value V1 and a current A/D converted value V...
Looking for a free and easy CFM calculator to determine how much compressed air your compressor is producing? Our online CFM calculator can help you properly size your air compressor and make sure you’ve got enough airflow to meet your compressed air de
The measurement of air flow – static pressure characteristics uses an auxiliary blower to control the pressure in chamber B, altering the pressure in chamber A. Thus, each point on the characteristics curve can be measured. Oriental Motor's measuring equipment is connected to a computer, providin...
2. Advection can be decomposed along the directions of the connected nodes based on the differential formula and the conservation of mass. We obtain the total convolutional operation to simulate the pollutant traffic on the graph space (Supplementary Fig. 1d): $$\frac{\partial C}{\partial t}...
For example, for combustion of gaseous fuels to find the volume of dry flue gases produced from burning a Nm3 of fuel, use the following formula: Vgu=CO(c)2+CO(c)+ΣmCmH(c)nCO(g.a)2+CO(g.a)+ΣmCmH(g.a)nVgu=CO2(c)+CO(c)+ΣmCmHn(c)CO2(g.a)+CO(g.a)+ΣmCmHn(g.a...
In the above formula the air density at the ground level of the Tehran International Tower was calculated. Its density on the other height was calculated by the same method and the results are shown in Table 6. It should be just mentioned that in the formula (R) is a constant parameter ...
According to the gas lubrication theory, Timoshenko’s thin film theory and the simulation figure of the pressure distribution of the air film flow field, the air load distribution model of the air film is established, and the deformation expression of the large liquid crystal glass substrate in...
When the conductive liquid moves along the measurement pipe axis, the conductive liquid cuts magnetic field lines and produces induced electromotive force, which can be measured by the two electrodes on the meter pipe. The result can be calculated by the formula: Wh...
