The management of a sugar factory decided to use an empty store room to keep the excess sugar. In order to preserve the quality of the sugar, the humidity of the store room must be below than 30%. As an engineer, you have tested the condition of the room with a sling psychrometer and found out the wet-bulb temperature and dry-bulb temperatures at 1 atm are 20 and 30°C, respectively. Given the specific heat at constant pressure is 1.005 kJ/kg-°C. Existing store Pre zd Empty store production A) Calculate the specific humidity and relative humidity of the empty store room. B) Estimate the enthalpy per unit mass and the masses of dry air as well as water vapor in the empty store room. C) In your opinion, is it possible to store the excess sugar in the empty store.as suggested by the factory management? Support your answer based on Thermodynamic Principles.

Question
The management of a sugar factory decided to use an empty store room to keep the
excess sugar. In order to preserve the quality of the sugar, the humidity of the store
room must be below than 30%. As an engineer, you have tested the condition of
the room with a sling psychrometer and found out the wet-bulb temperature and
dry-bulb temperatures at 1 atm are 20 and 30°C, respectively. Given the specific
heat at constant pressure is 1.005 kJ/kg-°C.
