The slurry occupies 70% of the total tank volume and the head space occupies the remaining 30%. The mean residence time of the slurry in the tank (which equals the volume of the slurry in the tank divided by the volumetric flow rate of the stream leaving the tank) is 12 minutes. Use this information, the quantities calculated in Problem 12.9, and the specific volume data given below to estimate the volume (m³) of slurry in the tank, the head space volume, and the total tank volume.
