Toluene presents the highest vapor specific volume, the lowest saturation pressure, and the least mass flow rate, leading to the smallest size of utilities, equipments, and the pump consumption among the three fluids.
The channel capacity is then, where is a constant; this must equal at least the total flow rate, so we obtain (7).
A gas or electric washer with a pressure rating of at least 3,000 PSI, and a flow rate of at least 4 gallons (15.1 L) per minute, will effectively clean exterior concrete.
The cost of inhaled agents is related to more than the amount taken up; it also depends on their market prices, their relative potencies, the amount of vapour released per millilitre of liquid, and last but not least the fresh-gas flow rate (FGF) delivered to the vaporizer the most important factor determining the cost of anaesthesia.
The net charge density appears to be relatively insensitive to the flow rate, at least for high flow rates.
Therefore ref. 38 recommends calibrating the flow rate at least every six months.
The spinal and nimesulide combination showed the lowest pain scores (p < 0.001), least reduction in peak expiratory flow rate (p < 0.001), and highest patient satisfaction rating (p = 0.02).
It is also preferable to use a pump able to provide a flow rate at least equal to that required for isokinetic sampling conditions in the fast loop.
The most effective parameters on the absorption of SO2 in TSC solutions were ranked to the least as solution concentration, gas flow rate, size of gas bubbles, absorption temperature and stirring rate.
The column was equilibrated with the mobile phase for at least 0.5 h at a flow rate of 0.8 mL/min before sample injection.
To establish a hydrogen peroxide concentration gradient with the least possible diffusion, the optimal flow rate through each inlet was investigated and determined to be 600 μL h−1, which was maintained constant throughout the whole flow device experiment (Supporting Information).
