function to determine the amount of acid to add to reach target tank conditions

Description

starts with a specified volume of water with specified chemistry conditions in then tank then calculates the amount of acid to add to reach target volume and chemistry

Usage

addAcid(
  initVol,
  initS,
  initT,
  initPH,
  targetVol,
  targetS,
  targetT,
  targetAlk,
  acidConc,
  pCO2,
  highSwater
)

Arguments

initVol	intial volume of water in the tank (L)
initS	intial salinity of water in the tank (psu)
initT	intial temperature of water in the tank (degrees C)
initPH	intial pH of water in the tank
targetVol	target volume of water in the tank (L)
targetS	target salinity (psu)
targetT	target temperature (degrees C)
targetAlk	target alkalinity (umol/kg)
acidConc	acid concentration (Normality)
pCO2	atmospheric pCO2 (uatm)
highSwater	salinity of the high salinty water to be added (psu)

Value

A list of the amount of acid to add and the final target pH #'

• totalAcidAddInit - total vol of acid needed to adjust only the inital water in the tank (ml)

• aaNewTotal - total vol of acid needed to adjust only the new water added to the tanks (ml)

• totalAcid

  • total volume of acid to add (= totalAcidAddInit + aaNewTotal) (ml) note: any of the acid additions could be negative (indcating the need to add base), however, the need for base should not occur when using instant ocean to create west coast water

  • finalPH - the target pH for the final solution (this will the the pH feedback setting)
