Density of Water = 1000 kg/m 3; 1 m 3 of Water = 1000 kg. Magnetite Density = 5170 kg/m 3. [image 145-3-29] [image 145-3-30] For example, a 400 tph feed to a dense medium process equates to a volumetric flow rate of 1000 gallons/min or 3.785 m 3 /min. At a 4:1 medium-to-coal ratio, the volume of medium is 15.14 m 3 /min.
