Question 4: Answer the following: (15 Marks) 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) (5 Marks) B) Using the results that obtained in section A) to estimate the rate of drying (kg/sec) for the constant rate period when the 2 is 2500 kJ/kg (10 Marks) jele beau 09 07 Lene of 2420 2400 2330 2300 2250 2200 Hurup This (kg S 05 100 105 1.10 1.18 1.29 1.25 210 TV XL ST R 9.12 610 890 9.07 80G shigig 8.00 0.04 9.00 8803 2732 275 260 3040 285 200 295 300 TO BO 130 140 150 7610 Temperature T 170 310 315 320 325 330 335 340 345 350 355 300 305 306 307 308 305 300 305 400 100 110 120 190 200 210 220 230 240 250 260 4 Hurgidity-temperature chart
