The Expression Pressure-Volume relationship is a fundamental model in Process Engineering used to predict the mechanical dewatering of porous, compressible solid cakes. This calculation is critical in industries such as food processing (e.g., fruit juice extraction from pomace), wastewater treatment (sludge dewatering), and chemical manufacturing (oilseed processing).
