Question 4: Answer the following: ( An insoluble wet granular material is dried in a pan 0.2 m² and 25 mm deep. Heat transfer is by convection from an air stream at a velocity 6 m/sec. The air is at 310 K and RH%-30%, it has density about 1.1 kg/m³. A) Using the figure below to calculate: 1) humidity (H), 2) humid heat (S), 3) temperature at dew point (Tdew), 4) temperature at wet point (Twet) and 5) latent heat (2.) (: B) Using the results that obtained in section A) to estimate the rate of drying (kg/sec) for the constant rate period when the . is 2500 kJ/kg (
