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

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
