What is the corrected standard air flow rate? , the slightly colder, denser air at standard conditions has greater buoyancy for the rotameter float ball). The square root function is used only for rotameters and critical orifice air flow meters, but never for dry and wet gas meters. Refer to Problem 311. ” Answer: 1. 1 × TLV (inmg /m 3 ) 2. Minimum sampling time (in hours) analytical sensitivity (m mg) = .

Density is essentially identical to specific gravity of a substance, the terms being normally interchangeable. For gases and vapors, air is often used as the reference. 997 g/cm3 at 25°C). Water is highly anomalous among liquids because it is denser at 4°C than at its freezing point of 0°C. Otherwise, ice sinks to the bottom of the lake! And life on Earth would be radically different than we know. Ice does not float because of entrained air bubbles—a common myth. Density calculations are used to determine the mass of a volume of liquid.
