AEN 340. Principles of Food Engineering Fall 2019 PROBLEM SET 10 DUE BY 11 AM ON NOVEMBER 10, 2019 30 POINTS 1. Estimate the relative humidity, specific volume, dew point, wet bulb temperature of air at 30°C dry bulb temperature and 0.01 kg of water/ kg of dry air? Use the psychrometric chart below to find the points and trace out (10 points) 2. Atmospheric air at 760 mm Hg is at 22°C dry bulb temperatures and 20°C wet bulb temperature. Using the psychrometric chart, determine (Show the exact location of this condition on a psychrometric chart and provide answers below) 10 points: a. Relative humidity: b. Humidity ratio. c. Dew-point temperature: d. Enthalpy of air per kg dry air: e. Volume of moist air/kg dry air. 3. On a copy of a psychrometric chart provided below, CLEARLY show the paths for heating and humidification process for the following data. Initially, the air is at a dry bulb temperature (dbt) of 40°C and a relative humidity of 30%. The air is heated to a dry bulb temperature of 55°C. The heated air is then conveyed through a humidifier to raise its relative humidity to 25%. For this process, calculate: a. The change in moisture content per kg of dry air: b. The change in enthalpy from the initial unheated air to final humidified air. 10 points AEN 340. Principles of Food Engineering Fall 2019 AEN 340. Principles of Food Engineering Fall 2019 AEN 340.
