Table of air properties at room temperature and pressure, simulating multiple measurements at approximately steady state,
Usage
data(air_meas, package = "formatdown")Format
Classes data.table and data.frame with 5 observations of 7 variables:
- date
"Date" class format "YYYY-MM-DD".
- trial
Character, label "a" through "e".
- humid
Factor, humidity, "low", "med", or "high."
- temp
Numeric, measured temperature (K).
- pres
Numeric, measured atmospheric pressure (Pa).
- sp_gas
Numeric, specific gas constant in mass form \(R_{sp}\), ideal gas reference value, (J kg\(^{-1}\)K\(^{-1}\)).
- dens
Numeric, calculated air density \(\rho\) = \(p\)\(R_{sp}^{-1}\)\(T^{-1}\) (kg m\(^{-3}\)).
