A container of acetone was accidently spilled, covering the top, smooth surface of a laboratory bench located in a semiconductor-fabrication building. The exhaust fan for the fabrication building produced a 6 m/s air flow parallel to the 1-m-wide bench surface. The air was maintained at 298 and 1:013 × 10⁵ Pa. The vapor pressure of acetone at 298 K 3:066 × 10⁴ Pa and the diffusivity of acetone in air at 298 K and 1:013 × 10⁵ Pa is 0:93 × 10^-5 m²/s.

(a) Determine the mass-transfer coefficient at 0.4 m downstream from the leading edge of the laboratory bench.

(b) Determine the amount of acetone evaporating per 1 m² of surface area each second.
