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, kef, lco.
flushing due to air flow l day-1 hcfla hcf * 60 * 24 / 1000
flushing due to gas exchange l day-1 hcflw kin * 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)
