Problem.1
A rotary drier using counter-current flow is to be used to dry 12000 kg/hr of wet salt containing 5% water (wet basis). Heated air at 147 Degree C with 50 Degree C wet bulb temp is available. The specific heat of the salt is 0.21. The outlet temp of air and salt are 72 degree C and 93 degree C respectively. Calculate the length and diameter of the drier required.
DATA::
Humidity of entering air = 0.05 kg water/kg dry air
Mass velocity of air = 5000 kg/hr-m2
Spe. Heat of salt = 0.21 kcal/kg. C
