Water quality blend model - Essay Example 3. (1/2 imprint) Convert the focuses to meq/L and compute the absolute meq/L of cations (positive) and anions (negative) and ascertain the â€Å"Charge balance error†. Does the CBE demonstrate an exact examination or should another example be dissected by the research facility? 4. (3 imprints) Assume that the â€Å"mine void† or V water is a blend of water from the coal crease C and an obscure source X. In the model with accessible information from a long divider coal mineshaft, water X could be S (sandstone rooftop) or water X could be F (freshwater). The blend extent M could be from 0.01 to 0.99.
