Question

An air-water vapor mixture containing 20% ​​humidity at a dry thermometer temperature of 40 ° C A tunnel is fed to the dryer by being heated to 70 ° C. Red pepper samples It is dried in adiabatic conditions. Leave the dryer system saturated For the mixing air-water vapor mixture, find the following.
a) 10000 m3 of moist air at 40 ° C (air-water vapor mixture) warmth Required heat to increase to 70 ° C
b) Air temperature at dryer outlet
c) Red of 10000 m3 of humid air (air-water vapor mixture) at 40 ° C temperature the amount of water to be removed from the peppers
d) The volume of moist air at the dryer outlet
Note: The path followed by the air-water vapor mixture during the heating and drying processes
show on psychrometric chart.
