Liquid benzene is contained at 298K in a 2 cm diameter glass tube and maintained at a level 5 cm below the top of the tube, which is open to atmosphere. The following properties of benzene are given: 1) Boiling temperature is 353K at 1 atm. 2) MW of benzene is 78.108 kg/kmol. 3) hfg is 393 kJ/kg at 353K. 4) Density is 879 kg/m^3 5) Diffusivity rate (D) is 0.88x10^-5 m^2/s at 298K. Determine the following: A) The mass evaporation rate of benzene knowing that Psat is 0.145 atm and Yf at infinity is zero B) How long does it take to evaporate 0.5 cm^3 of benzene QuestionLiquid benzene is contained at 298K in a 2 cmdiameter glass tube and maintained at a level 5cm below the top of the tube, which is open toatmosphere.
