Wet sawdust will be dried using air on a circular tray with a diameter of 10 cm and the variation of moisture content over time will be examined. The heat transfer coefficient was calculated as 0.64 cal/min.cm2.°C and the mass transfer coefficient as 3.86 g/cm2.min during the constant speed drying interval lasting 10 minutes. Calculate the dry bulb temperature since the absolute humidity of the air used for drying is 0.018 g water/g dry matter and the wet bulb temperature is 25°C. Additional data: Enthalpy of evaporation of water: 2442.3 kj/kg at 25°C Vapor pressure of water: 23.76 mm Hg at 25°C
