The optimum liquid alum dose from the jar tests is 10 mg/l. Determine the setting on the liquid alum chemical feeder in millilitres per minute when the flow is 1900GPM. The liquid alum delivered to the plant contains 642.3 milligrams of alum per millilitre of liquid solution

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
