tilavuusferkio
Tilavuusferkio is a theoretical quantity used in physics and engineering to quantify the fractional deviation of a defined volume from a reference volume under specified conditions. It is dimensionless and commonly defined as tilavuusferkio = (V − V0) / V0, with V the actual volume under operating conditions and V0 the reference volume, typically at a standard temperature and pressure.
In practice tilavuusferkio aggregates several sources of deviation from ideal conditions, including thermal expansion, compressibility, and
Applications: The concept is used in calibrating volumetric equipment, such as flasks, cylinders, and dosing systems,
Limitations: The linear decomposition assumes small deviations; for large ΔT or high pressures, nonlinear effects must
Example: A 1000 cm3 flask at 20 C with α ≈ 9×10^-5 /C and ΔT = 5 C yields f_th
Etymology: A compound of tilavuus (volume) and a suffix form denoting an error term; tilavuusferkio is a
