Wet and Dry Basis: Summary

The answers to the ConcepTests are given below and will open in a separate window. 
Key points from this module:
  • A wet basis includes all components in a stream, whereas a dry basis excludes water.
  • The moisture content of a stream is the moles of water divided by the total moles in the stream on a wet or dry basis, written as a percentage.
  • Mole balances can be used to interconvert between wet and dry basis. 
From studying this module, you should now be able to:
  • Distinguish between wet and dry bases and be able to analyze combustion reactions using either basis.
  • Calculate the moisture content of a stream on both a wet and a dry basis and interconvert between the two bases.
