Distillation can be used to separate solutions of miscible liquids because ?
by

1 Answer

Answer :

Distillation works because liquids boil at different temperatures. Roughly speaking, in order to separate two liquids, you should heat the mixture to a temperature where one of the liquids (but not the other) is past its boiling temperature. Then the first liquid will boil off, leaving the second liquid behind; you can collect the first liquid in a condenser.

When using a pumping loop to mix two miscible fluids in a tank, when can the content are considered well mixed?

Description : When using a pumping loop to mix two miscible fluids in a tank, when can the content are considered well mixed?

Last Answer : A rule of thumb is to turn the tank over three (3) times and then sample the tank for mixture properties. By “turn the tank over”, we mean to force the entire volume of the tank through the pump at least three times. More turnovers may be necessary, but three times is a good starting point.
