Material Balance A wet sample of a food product contains 20% moisture. It is required that this wet food sample is to be dried to a water content of 1%. This is achieved by circulating hot air over it. It was determined that the fresh air contains 0.018 kg water vapor per kg dry air while the exhaust air contains 0.095 kg water vapor per kg dry air. Based from the data given, calculate the volumetric flow rate of fresh air required for drying 1000 kg/h of wet solids if it is available at 300K and 101.325 kPa pressure.
