a) A spherical globule of glucose, 1/8 inch in diameter dissolved in water flowing a 6 sec. Given that the temperature of the water as 25 C (u= 0.9 cp, density of water ) = 1 gm/cm) and the diffusivity of glucose in water at 25 C as 4.124 x 10-3cm/sec. Calicut the mass transfer coefficient of glucose in water. b) The evaporation of liquid ammonia into the air at SOF and I aim. Given the heat transfer coefficient in the same apparatus and at the same liquid and gas flow rates as 810 Bar ft2 F). a) Estimate the mass transfer coefficient (kc) of liquid ammonia vaporizing into the air. b) Estimate the value of mass transfer coefficient (ko) if Prsc=1, what is % difference.
