Table 6-6: Non- steady state error

Quantity Units variable formula

The formulae below refer to the influx headspace.
For the efflux headspace substitute lcf, k_ef, lco.

flushing due to air flow l day^-1 hcfla hcf * 60 * 24 / 1000

flushing due to gas exchange l day^-1 hcflw k_in * a * area * 24 / 1000

headspace volume l airvol See Section 4.6.1

flushes (since last measurement) inflush timediff * ( hcflw + hcfla) / airvol

change in headspace pCO₂ ppm dhco hco - hco (previous measurement)

error in headspace pCO₂ ppm hcoerr dhco * exp (- inflush)
