Use the table below, it gives the solubility and permeability of the solid with different solute. Cellophane is a wrapping material widely used to keep fresh food at desired moist. Determine the loss of water vapor in mass flow rate at steady state for a wrapping 0.2 mm thick and an area of 0.4 m² when the vapor pressure of water vapor inside is 10 mmHg and air outside contain water vapor at a pressure of 5 mmHg. Assuming this process is being processed at 38°C and the smallest permeability is applied. Using the given properties: cellophane weighs 1,420 kg/m3 Permeability, PM me sobe STP msida Solute (A) Solid (B) H2 Vulcanized rubber 298 0.85(10 02 DAB Diffusion Solubility, S Coefficient m'solute (STP) T(K) (m²/s) m solid-am 0.040 9) 298 0.21(10 0.070 9) 298 0.15(10 0.035 9 298 0.11(10 0.90 9) 290 0.103(10 0.051 9 300 0.180(100.053 9) 0.342(10 19) 0.152(10- 19 0.05410 10 1.01(10-19) N2 CO2 H2 Vulcanized neoprene Polyethylene 298 H2 02 6.53(10-12) 4.17(10-12) 303 303 N2 O2 Nylon 303 N2 303 1.52(10-12) 0.029(10 12) 0.0152(10 12) 0.15-0.68 x 10+ 0.16(10-19 0.91 - 1.82(10-10) Air 298 English leather Wax 306 HO H2O Cellophane 311
