Stack loss data
===============

Description
-----------

The stack loss plant data of Brownlee (1965) contains
21 days of measurements from a plant's oxidation of ammonia to nitric acid.
The nitric oxide pollutants are captured in an absorption tower.

Notes
-----
::

    Number of Observations - 21

    Number of Variables - 4

    Variable name definitions::

        STACKLOSS - 10 times the percentage of ammonia going into the plant
                    that escapes from the absoroption column
        AIRFLOW   - Rate of operation of the plant
        WATERTEMP - Cooling water temperature in the absorption tower
        ACIDCONC  - Acid concentration of circulating acid minus 50 times 10.
