Design a drum for an extraction process. The input mass flow rate is 25000 kg/h with a mixture density of 850 kg/m3, and the residence time is 25 minutes when half full. The operation condition is pressure = 2 bar, and temperature = 200 C. Design the dimension of the drum (D and L), the thickness of the wall, and the type of material.
