Question

Q3. (20 marks) A thin film coat of fresh paint has been sprayed over a 1.5 m length of a drying chamber. The paint contains benzene as the solvent and needs to be evaporated. The surface of the paint exerts a partial pressure of 0.137 atm at 27 °C. The flowrate of air used for drying inside the chamber is 60 m³/min. The width and height of the chamber are 1.5 m and 1 m, respectively. Total pressure of the system is 1 atm. Find the evaporation rate of the solvent benzene in g/s. The following correlation is available: Sh = 0.664 \times Re^{0.5} Sc^{\frac{1}{3}}
