Outflow burning

In-cloud overpressure is dependent on outflow velocity, orifice diameter, and the fuel s laminar burning velocity. 

At the instant of time shown, the entrainment of air into the fire plume is 300 g/s, the outflow of smoke through the door is 295 g/s and the liquid fuel evaporation rate of a spill burning on the floor is 10 g/s. What is the mass rate of smoke accumulation within the room ... 

The process of making oil of vitriol, by burning sulphur under a hood fitted with a side tube for the outflow of the oil of vitriol, is represented in Fig. XIII. p. 92.

Independently of the measurements of the outflow curves, the amount of benzene dynamically adsorbed (ad) behind the adsorbent bed (after equilibration of concentration) was determined by weight. These values, expressed per unit of carbon volume are presented in Table 1. The maximum of benzene adsorption observed for AG40 carbon results both from the increase in the filling the carbon particles and the removal the layers with high burn-off from external surface. 

PTR-MS is now a well-established analytical technique in the environmental sciences, having a major impact on the detection and understanding of, for example, pollution outflow, biomass burning and sources of anthropogenic and biogenic VOCs in the atmosphere. However, it should be appreciated that when it was first introduced the PTR-MS findings were revolutionary, particularly since the fast time response enabled rapid changes in VOC emissions to be monitored. GC-MS techniques, which had been previously used to detect VOCs in the environment, are simply too slow to capture transient events on the minute-by-minute or faster timescale.
